Creates a bouncing loader animation.
|
|
|
|
- Use `@keyframes` to define a bouncing animation, using the `opacity` and `transform` properties. Use a single axis translation on `transform: translate3d()` to achieve better animation performance.
|
|
- Create a parent container, `.bouncing-loader`, for the bouncing circles. Use `display: flex` and `justify-content: center` to position them in the center.
|
|
- Give the three bouncing circle `<div>` elements the same `width` and `height` and `border-radius: 50%` to make them circular.
|
|
- Apply the `bouncing-loader` animation to each of the three bouncing circles.
|
|
- Use a different `animation-delay` for each circle and `animation-direction: alternate` to create the appropriate effect.
