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.

Box-sizing reset
