HTML-CSS: Bouncing loader

HTML-CSS : Exercise-13 with Solution

Using HTML, CSS create 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.
