1. `@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.

2. `.bouncing-loader` is the parent container of the bouncing circles and uses `display: flex` and `justify-content: center` to position them in the center.
|
||||
3. `.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.
|
||||
|
||||
4. `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.

5. `animation` is a shorthand property for the various animation properties: `animation-name`, `animation-duration`, `animation-iteration-count`, `animation-direction` are used.
|
||||
|
||||
6. `nth-child(n)` targets the element which is the nth child of its parent.

7. `animation-delay` is used on the second and third `div` respectively, so that each element does not start the animation at the same time.
