CSS样式更改——过渡、动画

div{transition: width 1s;-moz-transition: width 1s;  /* Firefox 4 */-webkit-transition: width 1s;  /* Safari 和 Chrome */-o-transition: width 1s;  /* Opera */}transition-property:应用过渡的Css属性的名称 比如宽度widthtransition-duration:过渡效果花费的时间   比如1stransition-timing-function:渡效果的时间曲线 如下所示：linear 匀速ease 先慢后快ease-in 慢速开始ease-out 慢速结束ease-in-out 慢速开始和结束cubic-bezier(n,n,n,n) 在cubic-bezie 函数中定义自己的值，可能的值是0至1之间的数值transition-delay:过渡效果何时开始 如1s
