style
div { width: 100px; height: 100px; background: red; -webkit-transition: width 2s, height 2s, -webkit-transform 2s; /* For Safari 3.1 to 6.0 */ transition: width 2s, height 2s, transform 2s;
} div:hover { width: 200px; height: 200px; -webkit-transform: rotate(180deg); /* Chrome, Safari, Opera */ transform: rotate(180deg);

二、CSS3动画
CSS3可以创建动画。keyframes规则是创建动画。keyframes规则内指定一个CSS样式和动画将逐步从目前的样式更改为新的样式。当在 keyframes 创建动画把它绑定到一个选择器否则动画不会有任何效果。指定至少这两个CSS3的动画属性绑定向一个选择器规定动画的名称规定动画的时长。如果省略持续时间动画将无法运行因为默认值是0。

div
{
width:100px;
height:100px;
