Frequently Asked Questions

@keyframes defines the intermediate steps in a CSS animation sequence. You specify styles at various percentages (0%–100%) and the browser smoothly interpolates between them.

Copy the @keyframes rule into your CSS file. Then apply animation: animation-name duration timing-function delay iteration-count direction fill-mode; to any element. You can customize the animation name in the code.

Ensure you specify both the 0% and 100% keyframes (or from/to). Missing percentage boundaries can cause abrupt jumps. Also verify that property values are consistent across keyframes (e.g., always use the same unit).

Absolutely. Add as many properties as you like inside each keyframe block. All properties will animate simultaneously. Use transform, opacity, background-color, width, etc.

Modern browsers all support unprefixed @keyframes. For very old browsers you may need to add -webkit- prefixes manually, but it's rarely necessary today.
