CSS3-旋转齿轮
查看DEMO
通过 CSS3，我们能够创建动画，这可以在许多网页中取代动画图片、Flash 动画以及 JavaScript。
先来认识一下css3的animation
animation的简写animation: name duration timing-function delay iteration-count direction;
**其次就是 at keyframes* *
好了，接下来运用上述两个属性做一个可以旋转的齿轮
<style> .img { margin: 0 auto; text-align: center; width: 400px; height: 400px; padding: 0; animation-name:myrotate; animation-duration:3s; animation-timing-function:linear; animation-delay:0s; animation-iteration-count:infinite; animation-direction:normal; animation-play-state:running; -moz-animation-name:myrotate; -moz-animation-duration:3s; -moz-animation-timing-function:linear; -moz-animation-delay:0s; -moz-animation-iteration-count:infinite; -moz-animation-direction:normal; -moz-animation-play-state:running; -webkit-animation-name:myrotate; -webkit-animation-duration:3s; -webkit-animation-timing-function:linear; -webkit-animation-delay:0s; -webkit-animation-iteration-count:infinite; -webkit-animation-direction:normal; -webkit-animation-play-state:running; -o-animation-name:myrotate; -o-animation-duration:3s; -o-animation-timing-function:linear; -o-animation-delay:0s; -o-animation-iteration-count:infinite; -o-animation-direction:normal; -o-animation-play-state:running; } @keyframes myrotate { from {transform: rotate(0deg);} to {transform: rotate(360deg);} } @-moz-keyframes myrotate { from {-moz-transform: rotate(0deg);} to {-moz-transform: rotate(360deg);} } @-webkit-keyframes myrotate { from {-webkit-transform: rotate(0deg);} to {-webkit-transform: rotate(360deg);} } @-o-keyframes myrotate { from {-o-transform: rotate(0deg);} to {-o-transform: rotate(360deg);} }</style><div class="img"> <img src="chilun.png" alt=""></div>
