1、transform: 旋转rotate、移动translate、缩放scale、扭曲skew
transform:rotate(±30deg) 正数:顺时针旋转,负数:逆时针旋转。 旋转
transform:translate(100px,20px) translateX translateY 平移
transform:scale(2,1.5) scaleX scaleY 缩放
transform:skew(30deg,10deg) skewX skewY 扭曲
2、transtion: all 1s ease;
1、ease:(逐渐变慢)
2、linear:(匀速)
3、ease-in:(加速)
4、ease-out:(减速)
5、ease-in-out:(加速然后减速)
3.@keyframes规则是创建动画。
.layer1 {
/*animation:动画名 动画时长;*/
animation:myfirst 3s;
}
@keyframes myfirst{
0% {background: red; left:0px; top:0px;}
25% {background: yellow; left:200px; top:0px;}
50% {background: blue; left:200px; top:200px;}
75% {background: green; left:0px; top:200px;}
100% {background: red; left:0px; top:0px;}
/*from{background:red}
to{background:yellow}*/
}
@-webkit-keyframes myfirst{ /* Safari and Chrome*/
0% {background: red; left:0px; top:0px;}
25% {background: yellow; left:200px; top:0px;}
50% {background: blue; left:200px; top:200px;}
75% {background: green; left:0px; top:200px;}
100% {background: red; left:0px; top:0px;}
/*from{background:red}
to{background:yellow}*/
}
@keyframes 规则和所有动画属性
@keyframes 规定动画
animation 所有动画属性的简写属性,除 animation-play-state
animation-name @keyframes 动画名称
animation-duration 动画完成一个周期所花秒或毫秒数。默认是 0
animation-timing-function 动画的速度曲线。默认是 "ease"
animation-delay 动画延迟多久开始。默认是 0
animation-iteration-count 规定动画被播放的次数。默认是 1
animation-direction 规定动画是否在下一周期逆向地播放。默认是 "normal"
animation-play-state 规定动画是否正在运行或暂停。默认是 "running"。
