ok,看看代码吧。
css:
代码如下:
*{margin:0; padding:0;}
body{padding:10px; font-size:12px;}
h1{margin:0; padding:10px 0; font-size:14px; font-weight:bold;}
a{background:url(1.gif) left 0; color:#fff; text-decoration:none; height:30px; float:left;
cursor:hand; margin:0 5px 0 0;}
a:hover{background:url(1.gif) left -30px;height:30px;}
a span{background:url(1.gif) right 0; padding:7px 8px 7px 0; margin:0 0 0 8px; float:left; height:16px;}
a:hover span{background:url(1.gif) right -30px; color:#000; padding:7px 8px 7px 0; margin:0 0 0 8px;
height:16px; }
html:
代码如下:
<body>
<h1><strong>css自适应宽度圆角按钮 @5key.net</strong></h1>
<a href="#"><span>首页</span></a>
<a href="#"><span>不是首页</span></a>
<a href="#"><span>他也许是首页</span></a>
<a href="#"><span>但他一定不是首页</span></a>
<a href="#"><span>好了,就这样把。别扯了~</span></a>
</body>
