css实现的点击具有立体背景变化效果的按钮:
一般来讲原生态的东西都比较粗放，网页中的按钮也是如此，下面就介绍一下美化按钮的方法，就是给链接设置一个背景图片，并且设置链接默认状态下和按下状态的背景图片，这样就实现我们想要的效果。
代码如下:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.clear{ overflow: hidden; width: 100%;}a.button{ background: transparent url('mytest/demo/bg_button_a.gif') no-repeat scroll top right; color:#444; display:block; float:left; font:normal 12px arial, sans-serif; height:24px; margin-right:6px; padding-right:18px; /* sliding doors padding */ text-decoration:none;}a.button span{ background:transparent url('mytest/demo/bg_button_span.gif') no-repeat; display:block; line-height:14px; padding:5px 0 5px 18px;}a.button:active{ background-position: bottom right; color:#000; outline:none;}a.button:active span { background-position:bottom left; padding:6px 0 4px 18px; }</style></head><body><a class="button" href="javascript:void(0);"><span>按钮</span></a></body></html>
