### CSS :not selector shortcut ### CSS :not selector shortcut
Lots of code just to space each item evenly, except for the last one is just one great example for the `:not` psuedo selector. The `:not` psuedo selector is perfect for styling a group of elements, and leaving the last (or specified) element unstyled without all the lines of code.
#### HTML #### HTML
```html ```html
<ul class="css-not-selector-shortcut">
<li class="link"><a href="">Link 1</a></li>
<li class="link"><a href="">Link 2</a></li>
<li class="link"><a href="">Link 3</a></li>
<li class="link"><a href="">Link 4</a></li>
<li class="link"><a href="">Link 5</a></li>
</ul>
``` ```
#### CSS #### CSS
```css ```css
li {
display: inline-block;
list-style-type: none;
margin: 0;
padding: .25em 1em;
}
.css-not-selector-shortcut a {
text-decoration:none;
color: #111111;
}
.css-not-selector-shortcut li:not(:last-child) {
border-right: 1px solid #666666;
}
``` ```
#### Demo #### Demo
<!-- You must create a `snippet-demo` parent block and use it as a namespace with BEM syntax. -->
<div class="snippet-demo"> <div class="snippet-demo">
<some-element class="snippet-demo__snippet-name"></some-element> <ul class="snippet-demo__css-not-selector-shortcut">
<li><a href="">Link 1</a></li>
<li><a href="">Link 2</a></li>
<li><a href="">Link 3</a></li>
<li><a href="">Link 4</a></li>
<li><a href="">Link 5</a></li>
</ul>
</div> </div>
<!-- Add your style rules here. -->
<style> <style>
li {
display: inline-block;
list-style-type: none;
margin: 0;
padding: .25em 1em;
}
.css-not-selector-shortcut a {
text-decoration:none;
color: #111111;
}
.css-not-selector-shortcut li:not(:last-child) {
border-right: 1px solid #666666;
}
</style> </style>
#### Explanation #### Explanation
<!-- Use a step-by-step (ordered) list if possible. Keep it concise. --> 1. Instead of putting on the border and then taking it off:
```css
.css-not-selector-shortcut li {
border-right: 1px solid #666666;
}
.css-not-selector-shortcut li:last-child {
border-right: none;
}
```
2. Use the `:not` psuedo selector to save a few lines:
```css
.css-not-selector-shortcut li:not(:last-child) {
border-right: 1px solid #666666;
}
```
