 Creates a bouncing loader animation.
 
-- `@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 `div`s of the parent to be styled. The `div`s 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.
-- Note that `1rem` is usually `16px`.
+- Use `@keyframes` to define an animation with two states, where the element changes `opacity` and is translated up on the 2D plane using `transform: translate3d()`. Use a single axis translation on `transform: translate3d()` to achieve better animation performance.
+- Create a parent container, `.bouncing-loader`, for the bouncing circles and use `display: flex` and `justify-content: center` to position them in the center.
+- Give the three bouncing circle `<div>` elements a `width` and `height` of `16px` and use `border-radius: 50%` to make them circular.
+- Apply the `bouncing-loader` animation to each of the three bouncing circles, using a different `animation-delay` for each one and `animation-direction: alternate` to create the appropriate effect.
