Retrieve or set the state of the object animation	3

@keyframes

is a rule of CSS3 that can be used to define the behavior of a period of CSS animation and create simple animations. @keyframes rules are composed of a set of encapsulated CSS style rules that describe how attribute values change over time.

@keyframes animation-name {keyframes-selector {css-styles;}}

@keyframe rules consist of the keyword "@keyframe", followed by an identifier giving the name of the animation (which will be referenced using animation-name), followed by a set of style rules (delimited by curly braces) . The animation is then applied to the element by using the identifier as the value of the animation-name attribute.

Syntax:

/* 定义动画*/
@keyframes 动画名称{
    /* 样式规则*/
}
/* 将它应用于元素 */
.element {
    animation-name: 动画名称（在@keyframes中已经声明好的）;
    /* 或使用动画简写属性*/
    animation: 动画名称 1s ...
}

Inside the curly braces, we need to define keyframes or waypoints that specify the value of the property being animated at a specific point during the animation . This allows us to control intermediate steps in the animation sequence.
