css @keyframes property syntax

@What are keyframes?

@keyframes is a rule of CSS that can be used to define the behavior of a period of CSS animation and create simple animations.

Function: Through the @keyframes rule, you can create animations.

Description: The principle of creating animation is to gradually change one set of CSS styles into another set of styles. You can change this set of CSS styles multiple times during the animation. Specifies when the change occurs as a percentage, or via the keywords "from" and "to", which are equivalent to 0% and 100%. 0% is the start time of the animation, 100% is the end time of the animation. For best browser support, you should always define 0% and 100% selectors.

Note: Please use the animation property to control the appearance of the animation and bind the animation to the selector.
