CSS Animation is a technique used to add movement and visual interest to web page elements. It allows you to animate the change of CSS styles over a specified duration of time. CSS animations can be used to create a wide range of effects, from simple hover animations to complex, multi-step animations.

Here’s an example of a basic CSS animation:

<code>@keyframes example {
  from {background-color: red;}
  to {background-color: yellow;}
}

element {
  animation-name: example;
  animation-duration: 2s;
}

In this example, the @keyframes rule sets the animation. The animation changes the background color of an element from red to yellow over a duration of 2 seconds. The animation-name and animation-duration properties are used to apply the animation to an element.

There are many other properties that can be used to control the behavior of CSS animations, such as animation-timing-function, animation-iteration-count, and animation-direction. These properties can be used to specify the speed and timing of the animation, as well as the number of times it should repeat and the direction in which it should play.

It’s also possible to animate multiple properties at once. For example:

@keyframes example {
  from {
    transform: rotate(0deg);
    opacity: 0;
  }
  to {
    transform: rotate(360deg);
    opacity: 1;
  }
}

element {
  animation-name: example;
  animation-duration: 2s;
}

In this example, the animation rotates an element 360 degrees and changes its opacity from 0 to 1 over a duration of 2 seconds.

CSS animations can be a powerful tool for creating engaging and interactive experiences on the web. However, they should be used judiciously, as they can have a significant impact on page performance and accessibility. It’s important to consider the impact of animations on page load time and user experience when deciding whether or not to use them.
