This article mainly describes how to use the CSS3 implementation of the sidebar to expand the animation, and attached the sample code, very detailed, recommended to the needs of the small partners.

@keyframes

Rules are used to create animations.

A CSS style is specified in the @keyframes to create an animated effect that changes from the current style to the new style.

When you create an animation in @keyframes, bundle it to a selector, or it will not animate.

You can bind an animation to a selector by stipulating at least the following two CSS3 animation properties:

Specify the name of the animation
Specify the duration of the animation
Animation
The animation property is a shorthand property that sets the animation properties:

Animation-name: Specifies the name of the @keyframes animation.
Animation-duration: Specifies the seconds or milliseconds that the animation takes to complete a cycle. The default is 0.
Animation-timing-function: Specifies the speed curve of the animation. The default is "ease".
Animation-delay: Specifies when the animation starts. Default is 0
Animation-iteration-count: Specifies the number of times the animation is played. The default is 1.
Animation-direction: Specifies whether the animation will play backwards in the next cycle. The default is "normal".
Animation-fill-mode: Specifies the state outside the animation time of the object
