What is CSS3 animation?

Animation is the effect of gradually changing elements from one style to another. Using the @ keyframes rule, you can create animations.

When you create an animation in @ keyframes, bind it to a selector, otherwise the animation will have no effect.

Specify that the animation properties of at least two CSS3 are bound to one selector:

● specifies the name of the animation

● specifies the length of animation.

Browser support

The number in the table represents the first browser version number that supports the property.

The number immediately before-webkit-,-ms- or-moz- is the first browser version number that supports the prefix attribute.

@ keyframes rule

Grammar.

@ keyframesanimationname {keyframes-selector {css-styles;}}

Attribute value:

Required for ● animationname. Defines the name of the animation.

Required for ● keyframes-selector. The percentage of animation duration.

Legal value:

● 0-100%

● from (same as 0%)

● to (same as 100%)

Required for ● css-styles. One or more legitimate CSS style attributes

Description:

You can change as many styles as you want and as many times as you like.

Please specify when the change occurs as a percentage, or use the keywords "from" and "to", which are equivalent to 0% and 100%.

0% is the beginning of the animation and 100% is the completion of the animation.

For optimal browser support, you should always define 0% and 100% selectors.
