关键专业知识点
① transform特性:
    ratate(转动度数)
    scale(等占比放缩)
    skew(x , y);让元素歪斜显示信息,包括两个主要参数值,各自表明X轴和Y轴歪斜的角度,假如第2个主要参数为空,则默认设置为0,主要参数为负表明向相反向歪斜。
②animate 可用于电脑鼠标历经造成宽度,高宽比,left,top这些 示例 transition:1s ease all;全部恶性事件造成动漫!

拷贝编码
编码以下:

div {
-webkit-animation-name: pulse;
-webkit-animation-duration: 2s;
-webkit-animation-iteration-count: infinite;
-webkit-animation-timing-function: ease-in-out;
-webkit-animation-direction: alternate;
}@-webkit-keyframes pulse {
from {
opacity: 0.0;
font-size: 100%;
}
to {
opacity: 1.0;
font-size: 200%;
}
}style
*{ margin: 0; padding: 0;}
body {
overflow: hidden;
}
#clouds{
background:-webkit-linear-gradient(top,#c9dbe9 0%,#fff 100%);/*等额的于background:-webkit-gradient(linear,left top,left bottom,from(c9dbe9),to(#fff))*/
background:-moz-linear-gradient(top,#c9dbe9 0%,#fff 100%);
background:-o-linear-gradient(top,#c9dbe9 0%,#fff 100%);
padding:100px 0px;
