- css动画的配置;
- animation-name :xx (设置关键帧的名称为xx);
- animation-duration:1s (动画持续时间为1s);
- animation-timing-function: linear (动画时间曲线:linear、ease(默认)、ease-in 、ease-out、ease-in-out、cubic-bezier(n,n,n,n) ) 。
- animation-delay:2s (动画等待2后开始);
- animatiom-iteration-count:infinite (动画播放次数);
- animation-direction:alternate(设置动画播放形式,规定动画是否在下一周期逆向地播放 nomal、reverse );
- animation-fill-mode: (动画结束的最后一帧,规定对象动画时间之外的状态);
- animation-play-state: (设置动画是否暂停);
- keyframes关键帧:一系列的keyframes(用来描述动画的开始、过程、结束状态);
