Previous Question Next Question

CSS @keyframes are used to define animations by specifying key points of an element's style during the animation sequence. These keyframes allow you to control the intermediate steps in an animation sequence by defining styles at specific moments.

Example Concept: The @keyframes rule in CSS is used to create animations by defining a sequence of style changes at specific points (keyframes) during the animation. You specify the styles at each keyframe, and the browser interpolates the styles between these points to create a smooth transition. For example, you can animate an element from one color to another or move it across the screen by defining keyframes at 0% and 100% (start and end) or at any percentage in between.

Additional Comment:

Animations are applied to elements using the "animation" property, where you specify the name of the @keyframes, duration, timing function, and other parameters.
Keyframes can be defined using percentages (0% to 100%) or with keywords like "from" and "to".
Multiple keyframes can be defined to create complex animations.
Browser support for @keyframes is broad, but always check for any vendor prefixes required for older browsers.
