Understanding
CSS Animations.

CSS animations make it possible to animate transitions from one CSS style configuration to another. They consist of two components: a set of keyframes that indicate the start and end states of the animation's style, and a set of properties describing the animation's timing.

Why use Keyframes?

Keyframes give you precise control over the intermediate steps in an animation sequence. You can define styles at 0%, 50%, or any custom percentage.

Performance Benefits

CSS animations are often hardware-accelerated. By using properties like transform and opacity, you can achieve 60FPS animations without heavy JavaScript logic.

Best Practices

  • 1Keep animations subtle and avoid "over-animating" elements which can distract users.
  • 2Always provide a mechanism to pause or stop long-running animations for accessibility (WCAG compliance).
  • 3Use `will-change` sparingly to help browsers optimize for upcoming animations.
