+
+li::before {
+ counter-increment: counter;
+ content: counters(counter, '.') ' ';
+}
+```
+
+
+#### Explanation
+
+
+You can create a ordered list using any type of HTML.
+
+1. `counter-reset` Initializes a counter, the value is the name of the counter. By default, the counter starts at 0. This property can also be used to change its value to any specific number.
+
+2. `counter-increment` Used in element that will be countable. Once `counter-reset` initialized, a counter's value can be increased or decreased.
+
+3. `counter(name, style)` Displays the value of a section counter. Generally used in a `content` property. This function can receive two parameters, the first as the name of the counter and the second one can be `decimal` or `upper-roman` (`decimal` by default).
+
+4. `counters(counter, string, style)` Displays the value of a section counter. Generally used in a `content` property. This function can receive three parameters, the first as the name of the counter, the second one you can include a string which comes after the counter and the third one can be `decimal` or `upper-roman` (`decimal` by default).
+
+5. A CSS counter can be especially useful for making outlined lists, because a new instance of the counter is automatically created in child elements. Using the `counters()` function, separating text can be inserted between different levels of nested counters.

+ opacity: 0.7;
+ z-index: -1;
+}
+```
+
+
+#### Explanation
+
+
+1. `position: relative` on the element establishes a Cartesian positioning context for psuedo-elements.
+2. `z-index: 1` establishes a new stacking context.
+3. `::after` defines a pseudo-element.
+4. `position: absolute` takes the pseudo element out of the flow of the document and positions it in relation to the parent.
+5. `width: 100%` and `height: 100%` sizes the pseudo-element to fill its parent's dimensions, making it equal in size.
+6. `background: inherit` causes the pseudo-element to inherit the linear gradient specified on the element.
+7. `top: 0.5rem` offsets the pseudo-element down slightly from its parent.
+8. `filter: blur(0.4rem)` will blur the pseudo-element to create the appearance of a shadow underneath.
+9. `opacity: 0.7` makes the pseudo-element partially transparent.
+10. `z-index: -1` positions the pseudo-element behind the parent but in front of the background.

+ background-color: rgba(0, 150, 255, 0.3);
+ text-shadow: none;
+}
+```
+
+
+#### Explanation
+
+
+1. `text-shadow` uses 4 values with offsets that cover a 4x4 px area to ensure the underline
+ has a "thick" shadow that covers the line where descenders clip it. Use a color
+ that matches the background. For a larger font, use a larger `px` size. Additional values
+ can create an even thicker shadow, and subpixel values can also be used.
+2. `background-image: linear-gradient(...)` creates a 90deg gradient using the
+ text color (`currentColor`).
+3. The `background-*` properties size the gradient as 100% of the width of the block and 1px
+ in height at the bottom and disables repetition, which creates a 1px underline beneath
+ the text.
+4. The `::selection` pseudo selector rule ensures the text shadow does not interfere with text
+ selection.

+ position: absolute;
+ width: 100%;
+ height: 12px;
+ bottom: 0;
+}
+```
+
+
+#### Explanation
+
+
+1. `position: relative` on the element establishes a Cartesian positioning context for pseudo elements.
+2. `::after` defines a pseudo element.
+3. `background-image: url(...)` adds the SVG shape (a 24x12 triangle) as the background image of the pseudo element, which repeats by default. It must be the same color as the block that is being separated. For other shapes, we can use [the URL-encoder for SVG](http://yoksel.github.io/url-encoder/).
+4. `position: absolute` takes the pseudo element out of the flow of the document and positions it in relation to the parent.
+5. `width: 100%` ensures the element stretches the entire width of its parent.
+6. `height: 12px` is the same height as the shape.
+7. `bottom: 0` positions the pseudo element at the bottom of the parent.

-Demo Explanation Note: 1rem is usually 16px.
@keyframes defines an animation that has two states, where the element changes opacity and is translated up on the 2D plane using transform: translate3d(). Using a single axis translation on transform: translate3d() improves the performance of the animation.
.bouncing-loader is the parent container of the bouncing circles and uses display: flex and justify-content: center to position them in the center.
.bouncing-loader > div, targets the three child divs of the parent to be styled. The divs are given a width and height of 1rem, using border-radius: 50% to turn them from squares to circles.
margin: 3rem 0.2rem specifies that each circle has a top/bottom margin of 3rem and left/right margin of 0.2rem so that they do not directly touch each other, giving them some breathing room.
animation is a shorthand property for the various animation properties: animation-name, animation-duration, animation-iteration-count, animation-direction are used.
nth-child(n) targets the element which is the nth child of its parent.
animation-delay is used on the second and third div respectively, so that each element does not start the animation at the same time.

Browser support Calc() The function calc() allows to define CSS values with the use of mathematical expressions, the value adopted for the property is the result of a mathematical expression.
HTML <div class="box-example"></div>
-CSS .box-example {
- height: 280px;
- background: #222 url('https://image.ibb.co/fUL9nS/wolf.png') no-repeat;
- background-position: calc(100% - 20px) calc(100% - 20px);
-}
-Demo If you want to align a background-image from right and bottom wasn't possible with just straight length values. So now it's possible using calc():
Background-image in the right/bottom
Explanation It allows addition, subtraction, multiplication and division. Can use different units (pixel and percent together, for example) for each value in your expression. It is permitted to nest calc() functions. It can be used in any property that <length>, <frequency>, <angle>, <time>, <number>, <color>, or <integer> is allowed, like width, height, font-size, top, left, etc. Browser support Circle Creates a circle shape with pure CSS.
HTML <div class="circle"></div>
-CSS .circle {
- border-radius: 50%;
- width: 2rem;
- height: 2rem;
- background: #333;
-}
-Demo Explanation border-radius: 50% curves the borders of an element to create a circle.
Since a circle has the same radius at any given point, the width and height must be the same. Differing values will create an ellipse.
Browser support Clearfix Ensures that an element self-clears its children.
Note: This is only useful if you are still using float to build layouts. Please consider using a modern approach with flexbox layout or grid layout. HTML <div class="clearfix">
- <div class="floated">float a</div>
- <div class="floated">float b</div>
- <div class="floated">float c</div>
-</div>
-CSS .clearfix::after {
- content: '';
- display: block;
- clear: both;
-}
-.floated {
- float: left;
-}
-Demo Explanation .clearfix::after defines a pseudo-element.content: '' allows the pseudo-element to affect layout.clear: both indicates that the left, right or both sides of the element cannot be adjacent to earlier floated elements within the same block formatting context. Browser support ⚠️ For this snippet to work properly you need to ensure that there are no non-floating children in the container and that there are no tall floats before the clearfixed container but in the same formatting context (e.g. floated columns).
Constant width to height ratio Given an element of variable width, it will ensure its height remains proportionate in a responsive fashion (i.e., its width to height ratio remains constant).
HTML <div class="constant-width-to-height-ratio"></div>
-CSS .constant-width-to-height-ratio {
- background: #333;
- width: 50%;
-}
-.constant-width-to-height-ratio::before {
- content: '';
- padding-top: 100%;
- float: left;
-}
-.constant-width-to-height-ratio::after {
- content: '';
- display: block;
- clear: both;
-}
-Demo Explanation padding-top on the ::before pseudo-element causes the height of the element to equal a percentage of its width. 100% therefore means the element's height will always be 100% of the width, creating a responsive square.
This method also allows content to be placed inside the element normally.
Browser support Counter Counters are, in essence, variables maintained by CSS whose values may be incremented by CSS rules to track how many times they're used.
HTML <ul>
- <li>List item</li>
- <li>List item</li>
- <li>
- List item
- <ul>
- <li>List item</li>
- <li>List item</li>
- <li>List item</li>
- </ul>
- </li>
-</ul>
-CSS ul {
- counter-reset: counter;
-}
-li::before {
- counter-increment: counter;
- content: counters(counter, '.') ' ';
-}
-Demo List item List item List item List item List item List item Explanation You can create a ordered list using any type of HTML.
counter-reset Initializes a counter, the value is the name of the counter. By default, the counter starts at 0. This property can also be used to change its value to any specific number.
counter-increment Used in element that will be countable. Once counter-reset initialized, a counter's value can be increased or decreased.
counter(name, style) Displays the value of a section counter. Generally used in a content property. This function can receive two parameters, the first as the name of the counter and the second one can be decimal or upper-roman (decimal by default).
counters(counter, string, style) Displays the value of a section counter. Generally used in a content property. This function can receive three parameters, the first as the name of the counter, the second one you can include a string which comes after the counter and the third one can be decimal or upper-roman (decimal by default).
A CSS counter can be especially useful for making outlined lists, because a new instance of the counter is automatically created in child elements. Using the counters() function, separating text can be inserted between different levels of nested counters.
Browser support Customizes the scrollbar style for the document and elements with scrollable overflow, on WebKit platforms.
HTML <div class="custom-scrollbar">
- <p>
- Lorem ipsum dolor sit amet consectetur adipisicing elit.<br />
- Iure id exercitationem nulla qui repellat laborum vitae, <br />
- molestias tempora velit natus. Quas, assumenda nisi. <br />
- Quisquam enim qui iure, consequatur velit sit?
- </p>
-</div>
-CSS .custom-scrollbar {
- height: 70px;
- overflow-y: scroll;
-}
-/* To style the document scrollbar, remove `.custom-scrollbar` */
-.custom-scrollbar::-webkit-scrollbar {
- width: 8px;
-}
-.custom-scrollbar::-webkit-scrollbar-track {
- box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
- border-radius: 10px;
-}
-.custom-scrollbar::-webkit-scrollbar-thumb {
- border-radius: 10px;
- box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.5);
-}
-Demo Explanation ::-webkit-scrollbar targets the whole scrollbar element.::-webkit-scrollbar-track targets only the scrollbar track.::-webkit-scrollbar-thumb targets the scrollbar thumb. There are many other pseudo-elements that you can use to style scrollbars. For more info, visit the WebKit Blog .
Browser support ⚠️ Scrollbar styling doesn't appear to be on any standards track.
Custom text selection Changes the styling of text selection.
HTML <p class="custom-text-selection">Select some of this text.</p>
-CSS ::selection {
- background: aquamarine;
- color: black;
-}
-.custom-text-selection::selection {
- background: deeppink;
- color: white;
-}
-Demo Select some of this text.
Explanation ::selection defines a pseudo selector on an element to style text within it when selected. Note that if you don't combine any other selector your style will be applied at document root level, to any selectable element.
Browser support ⚠️ Requires prefixes for full support and is not actually in any specification.
Custom variables CSS variables that contain specific values to be reused throughout a document.
HTML <p class="custom-variables">CSS is awesome!</p>
-CSS :root {
- /* Place variables within here to use the variables globally. */
-}
-.custom-variables {
- --some-color: #da7800;
- --some-keyword: italic;
- --some-size: 1.25em;
- --some-complex-value: 1px 1px 2px whitesmoke, 0 0 1em slategray, 0 0 0.2em slategray;
- color: var(--some-color);
- font-size: var(--some-size);
- font-style: var(--some-keyword);
- text-shadow: var(--some-complex-value);
-}
-Demo Explanation The variables are defined globally within the :root CSS pseudo-class which matches the root element of a tree representing the document. Variables can also be scoped to a selector if defined within the block.
Declare a variable with --variable-name:.
Reuse variables throughout the document using the var(--variable-name) function.
Browser support Disable selection Makes the content unselectable.
HTML <p>You can select me.</p>
-<p class="unselectable">You can't select me!</p>
-CSS .unselectable {
- user-select: none;
-}
-Demo You can select me.
You can't select me!
Explanation user-select: none specifies that the text cannot be selected.
Browser support ⚠️ Requires prefixes for full support. ⚠️ This is not a secure method to prevent users from copying content.
Display table centering Vertically and horizontally centers a child element within its parent element using display: table (as an alternative to flexbox).
HTML <div class="container">
- <div class="center"><span>Centered content</span></div>
-</div>
-CSS .container {
- border: 1px solid #333;
- height: 250px;
- width: 250px;
-}
-.center {
- display: table;
- height: 100%;
- width: 100%;
-}
-.center > span {
- display: table-cell;
- text-align: center;
- vertical-align: middle;
-}
-Demo Explanation display: table on '.center' allows the element to behave like a <table> HTML element.100% height and width on '.center' allows the element to fill the available space within its parent element. display: table-cell on '.center > span' allows the element to behave like an HTML element.text-align: center on '.center > span' centers the child element horizontally.vertical-align: middle on '.center > span' centers the child element vertically. The outer parent ('.container' in this case) must have a fixed height and width.
Browser support Donut spinner Creates a donut spinner that can be used to indicate the loading of content.
HTML <div class="donut"></div>
-CSS @keyframes donut-spin {
- 0% {
- transform: rotate(0deg);
- }

- position: absolute;
- background: inherit;
- top: 0.5rem;
- filter: blur(0.4rem);
- opacity: 0.7;
- z-index: -1;
-}
-Demo Explanation position: relative on the element establishes a Cartesian positioning context for psuedo-elements.z-index: 1 establishes a new stacking context.::after defines a pseudo-element.position: absolute takes the pseudo element out of the flow of the document and positions it in relation to the parent.width: 100% and height: 100% sizes the pseudo-element to fill its parent's dimensions, making it equal in size.background: inherit causes the pseudo-element to inherit the linear gradient specified on the element.top: 0.5rem offsets the pseudo-element down slightly from its parent.filter: blur(0.4rem) will blur the pseudo-element to create the appearance of a shadow underneath.opacity: 0.7 makes the pseudo-element partially transparent.z-index: -1 positions the pseudo-element behind the parent but in front of the background. Browser support ⚠️ Requires prefixes for full support.
Easing variables Variables that can be reused for transition-timing-function properties, more powerful than the built-in ease, ease-in, ease-out and ease-in-out.

-}
-JavaScript var el = document.querySelector('.el')
-var height = el.scrollHeight
-el.style.setProperty('--max-height', height + 'px')
-Demo Hover me to see a height transition.
content
Explanation CSS transition: max-height: 0.5s cubic-bezier(...) specifies that changes to max-height should be transitioned over 0.5 seconds, using an ease-out-quint timing function.overflow: hidden prevents the contents of the hidden element from overflowing its container.max-height: 0 specifies that the element has no height initially..target:hover > .el specifies that when the parent is hovered over, target a child .el within it and use the --max-height variable which was defined by JavaScript. JavaScript el.scrollHeight is the height of the element including overflow, which will change dynamically based on the content of the element.el.style.setProperty(...) sets the --max-height CSS variable which is used to specify the max-height of the element the target is hovered over, allowing it to transition smoothly from 0 to auto. Browser Support
Requires JavaScript
⚠️ Causes reflow on each animation frame, which will be laggy if there are a large number of elements beneath the element that is transitioning in height.

Explanation display: inline-block makes the block p an inline-block to prevent the underline from spanning the entire parent width rather than just the content (text).position: relative on the element establishes a Cartesian positioning context for pseudo-elements.::after defines a pseudo-element.position: absolute takes the pseudo element out of the flow of the document and positions it in relation to the parent.width: 100% ensures the pseudo-element spans the entire width of the text block.transform: scaleX(0) initially scales the pseudo element to 0 so it has no width and is not visible.bottom: 0 and left: 0 position it to the bottom left of the block.transition: transform 0.25s ease-out means changes to transform will be transitioned over 0.25 seconds with an ease-out timing function.transform-origin: bottom right means the transform anchor point is positioned at the bottom right of the block.:hover::after then uses scaleX(1) to transition the width to 100%, then changes the transform-origin to bottom left so that the anchor point is reversed, allowing it transition out in the other direction when hovered off. Browser support Last item with remaining available height Take advantage of available viewport space by giving the last element the remaining available space in current viewport, even when resizing the window.

-Demo Explanation height: 100% set the height of container as viewport height.display: flex enables flexbox.flex-direction: column set the direction of flex items' order from top to down.flex-grow: 1 the flexbox will apply remaining available space of container to last child element. The parent must have a viewport height. flex-grow: 1 could be applied to the first or second element, which will have all available space.

Requires JavaScript
⚠️ Requires JavaScript.
:not selector The :not psuedo selector is useful for styling a group of elements, while leaving the last (or specified) element unstyled.
HTML <ul class="css-not-selector-shortcut">
- <li>One</li>
- <li>Two</li>
- <li>Three</li>
- <li>Four</li>
-</ul>
-CSS .css-not-selector-shortcut {
- display: flex;
-}
-ul {
- padding-left: 0;
-}
-li {
- list-style-type: none;
- margin: 0;
- padding: 0 0.75rem;
-}
-li:not(:last-child) {
- border-right: 2px solid #d2d5e4;
-}
-Demo Explanation li:not(:last-child) specifies that the styles should apply to all li elements except the :last-child.
Browser support Offscreen A bulletproof way to completely hide an element visually and positionally in the DOM while still allowing it to be accessed by JavaScript and readable by screen readers. This method is very useful for accessibility (ADA ) development when more context is needed for visually-impaired users. As an alternative to display: none which is not readable by screen readers or visibility: hidden which takes up physical space in the DOM.
HTML <a class="button" href="http://pantswebsite.com">
- Learn More <span class="offscreen"> about pants</span>
-</a>
-CSS .offscreen {
- border: 0;
- clip: rect(0 0 0 0);
- height: 1px;
- margin: -1px;
- overflow: hidden;
- padding: 0;
- position: absolute;
- width: 1px;
-}
-Demo Explanation Remove all borders. Use clip to indicate that no part of the element should be shown. Make the height and width of the element 1px. Negate the elements height and width using margin: -1px. Hide the element's overflow. Remove all padding. Position the element absolutely so that it does not take up space in the DOM. Browser support (Although clip technically has been depreciated, the newer clip-path currently has very limited browser support.)
Adds a fading gradient to an overflowing element to better indicate there is more content to be scrolled.

-Demo Explanation position: relative on the parent establishes a Cartesian positioning context for pseudo-elements.::after defines a pseudo element.background-image: linear-gradient(...) adds a linear gradient that fades from transparent to white (top to bottom).position: absolute takes the pseudo element out of the flow of the document and positions it in relation to the parent.width: 240px matches the size of the scrolling element (which is a child of the parent that has the pseudo element).height: 25px is the height of the fading gradient pseudo-element, which should be kept relatively small.bottom: 0 positions the pseudo-element at the bottom of the parent.pointer-events: none specifies that the pseudo-element cannot be a target of mouse events, allowing text behind it to still be selectable/interactive. Browser support Reveals an interactive popout menu on hover and focus.

-}
-.reference:hover > .popout-menu,
-.reference:focus > .popout-menu,
-.reference:focus-within > .popout-menu {
- visibility: visible;
-}
-Demo Explanation position: relative on the reference parent establishes a Cartesian positioning context for its child.position: absolute takes the popout menu out of the flow of the document and positions it in relation to the parent.left: 100% moves the the popout menu 100% of its parent's width from the left.visibility: hidden hides the popout menu initially and allows for transitions (unlike display: none)..reference:hover > .popout-menu means that when .reference is hovered over, select immediate children with a class of .popout-menu and change their visibility to visible, which shows the popout..reference:focus > .popout-menu means that when .reference is focused, the popout would be shown..reference:focus-within > .popout-menu ensures that the popout is shown when the focus is within the reference. Browser support Pretty text underline A nicer alternative to text-decoration: underline or <u></u> where descenders do not clip the underline. Natively implemented as text-decoration-skip-ink: auto but it has less control over the underline.
HTML <p class="pretty-text-underline">Pretty text underline without clipping descending letters.</p>
-CSS .pretty-text-underline {
- display: inline;
- text-shadow: 1px 1px #f5f6f9, -1px 1px #f5f6f9, -1px -1px #f5f6f9, 1px -1px #f5f6f9;

-}
-.pretty-text-underline::selection {
- background-color: rgba(0, 150, 255, 0.3);
- text-shadow: none;
-}
-Demo Pretty text underline without clipping descending letters.
Explanation text-shadow uses 4 values with offsets that cover a 4x4 px area to ensure the underline has a "thick" shadow that covers the line where descenders clip it. Use a color that matches the background. For a larger font, use a larger px size. Additional values can create an even thicker shadow, and subpixel values can also be used.background-image: linear-gradient(...) creates a 90deg gradient using the text color (currentColor).The background-* properties size the gradient as 100% of the width of the block and 1px in height at the bottom and disables repetition, which creates a 1px underline beneath the text. The ::selection pseudo selector rule ensures the text shadow does not interfere with text selection. Browser support Reset all styles Resets all styles to default values with one property. This will not affect direction and unicode-bidi properties.
HTML <div class="reset-all-styles">

-Demo Title Lorem ipsum dolor sit amet consectetur adipisicing elit. Iure id exercitationem nulla qui repellat laborum vitae, molestias tempora velit natus. Quas, assumenda nisi. Quisquam enim qui iure, consequatur velit sit?
Explanation The all property allows you to reset all styles (inherited or not) to default values.
Browser support ⚠️ MS Edge status is under consideration.
Shape separator Uses an SVG shape to separate two different blocks to create more a interesting visual appearance compared to standard horizontal separation.
HTML <div class="shape-separator"></div>
-CSS .shape-separator {
- position: relative;
- height: 48px;
- background: #333;
-}
-.shape-separator::after {

- position: absolute;
- width: 100%;
- height: 12px;
- bottom: 0;
-}
-Demo Explanation position: relative on the element establishes a Cartesian positioning context for pseudo elements.::after defines a pseudo element.background-image: url(...) adds the SVG shape (a 24x12 triangle) as the background image of the pseudo element, which repeats by default. It must be the same color as the block that is being separated. For other shapes, we can use the URL-encoder for SVG .position: absolute takes the pseudo element out of the flow of the document and positions it in relation to the parent.width: 100% ensures the element stretches the entire width of its parent.height: 12px is the same height as the shape.bottom: 0 positions the pseudo element at the bottom of the parent. Browser support Sibling fade Fades out the siblings of a hovered item.
HTML <div class="sibling-fade">
- <span>Item 1</span> <span>Item 2</span> <span>Item 3</span> <span>Item 4</span>

-CSS span {
- padding: 0 1rem;
- transition: opacity 0.2s;
-}
-.sibling-fade:hover span:not(:hover) {
- opacity: 0.5;
-}
-Demo Item 1 Item 2 Item 3 Item 4 Item 5 Item 6
Explanation transition: opacity 0.2s specifies that changes to opacity will be transitioned over 0.2 seconds..sibling-fade:hover span:not(:hover) specifies that when the parent is hovered, select any span children that are not currently being hovered and change their opacity to 0.5. Browser support System font stack Uses the native font of the operating system to get close to a native app feel.
HTML <p class="system-font-stack">This text uses the system font.</p>
-CSS .system-font-stack {
- font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu,
- Cantarell, 'Helvetica Neue', Helvetica, Arial, sans-serif;
-}
-Demo This text uses the system font.
Explanation The browser looks for each successive font, preferring the first one if possible, and falls back to the next if it cannot find the font (on the system or defined in CSS).
-apple-system is San Francisco, used on iOS and macOS (not Chrome however)BlinkMacSystemFont is San Francisco, used on macOS ChromeSegoe UI is used on Windows 10Roboto is used on AndroidOxygen-Sans is used on Linux with KDEUbuntu is used on Ubuntu (all variants)Cantarell is used on Linux with GNOME Shell"Helvetica Neue" and Helvetica is used on macOS 10.10 and below (wrapped in quotes because it has a space)Arial is a font widely supported by all operating systemssans-serif is the fallback sans-serif font if none of the other fonts are supported Browser support Toggle switch Creates a toggle switch with CSS only.
HTML <input type="checkbox" id="toggle" class="offscreen" /> <label for="toggle" class="switch"></label>
-CSS .switch {
- position: relative;
- display: inline-block;
- width: 40px;
- height: 20px;
- background-color: rgba(0, 0, 0, 0.25);
- border-radius: 20px;
- transition: all 0.3s;
-}
-.switch::after {
- content: '';
- position: absolute;
- width: 18px;
- height: 18px;
- border-radius: 18px;
- background-color: white;
- top: 1px;
- left: 1px;
- transition: all 0.3s;
-}
-input[type='checkbox']:checked + .switch::after {
- transform: translateX(20px);
-}
-input[type='checkbox']:checked + .switch {
- background-color: #7983ff;
-}
-.offscreen {
- position: absolute;
- left: -9999px;
-}
-Demo
Explanation This effect is styling only the <label> element to look like a toggle switch, and hiding the actual <input> checkbox by positioning it offscreen. When clicking the label associated with the <input> element, it sets the <input> checkbox into the :checked state.
The for attribute associates the <label> with the appropriate <input> checkbox element by its id. .switch::after defines a pseudo-element for the <label> to create the circular knob.input[type='checkbox']:checked + .switch::after targets the <label>'s pseudo-element's style when the checkbox is checked.transform: translateX(20px) moves the pseudo-element (knob) 20px to the right when the checkbox is checked.background-color: #7983ff; sets the background-color of the switch to a different color when the checkbox is checked..offscreen moves the <input> checkbox element, which does not comprise any part of the actual toggle switch, out of the flow of document and positions it far away from the view, but does not hide it so it is accessible via keyboard and screen readers.transition: all 0.3s specifies all property changes will be transitioned over 0.3 seconds, therefore transitioning the <label>'s background-color and the pseudo-element's transform property when the checkbox is checked. Browser support ⚠️ Requires prefixes for full support.
Vertically and horizontally centers a child element within its parent element using position: absolute and transform: translate() (as an alternative to flexbox or display: table). Similar to flexbox, this method does not require you to know the height or width of your parent or child so it is ideal for responsive applications.
HTML <div class="parent"><div class="child">Centered content</div></div>
-CSS .parent {
- border: 1px solid #333;
- height: 250px;
- position: relative;
- width: 250px;
-}
-.child {
- left: 50%;
- position: absolute;
- top: 50%;
- transform: translate(-50%, -50%);
- text-align: center;
-}
-Demo Explanation position: absolute on the child element allows it to be positioned based on its containing block.left: 50% and top: 50% offsets the child 50% from the left and top edge of its containing block.transform: translate(-50%, -50%) allows the height and width of the child element to be negated so that it is vertically and horizontally centered. Note: Fixed height and width on parent element is for the demo only.

Triangle Creates a triangle shape with pure CSS.
HTML <div class="triangle"></div>
-CSS .triangle {
- width: 0;
- height: 0;
- border-top: 20px solid #333;
- border-left: 20px solid transparent;
- border-right: 20px solid transparent;
-}
-Demo Explanation View this link for a detailed explanation.
The color of the border is the color of the triangle. The side the triangle tip points corresponds to the opposite border-* property. For example, a color on border-top means the arrow points downward.
Experiment with the px values to change the proportion of the triangle.

Explanation overflow: hidden prevents the text from overflowing its dimensions (for a block, 100% width and auto height).width: 400px ensures the element has a dimension.height: 109.2px calculated value for height, it equals font-size * line-height * numberOfLines (in this case 26 * 1.4 * 3 = 109.2)height: 36.4px calculated value for gradient container, it equals font-size * line-height (in this case 26 * 1.4 = 36.4)background: linear-gradient(to right, rgba(0, 0, 0, 0), #f5f6f9 50%) gradient from transparent to #f5f6f9 Browser support Truncate text If the text is longer than one line, it will be truncated and end with an ellipsis ….
HTML <p class="truncate-text">If I exceed one line's width, I will be truncated.</p>
-CSS .truncate-text {
- overflow: hidden;
- white-space: nowrap;
- text-overflow: ellipsis;

-}
-Demo If I exceed one line's width, I will be truncated.
Explanation overflow: hidden prevents the text from overflowing its dimensions (for a block, 100% width and auto height).white-space: nowrap prevents the text from exceeding one line in height.text-overflow: ellipsis makes it so that if the text exceeds its dimensions, it will end with an ellipsis.width: 200px; ensures the element has a dimension, to know when to get ellipsis Browser support ⚠️ Only works for single line elements.
Zebra striped list Creates a striped list with alternating background colors, which is useful for differentiating siblings that have content spread across a wide row.
HTML <ul>
