tab 是在css当中一个自定义的类。通常定义在网页的<style></style>之间。比如:<head>
<style type="text/css">
.tab { font-size:12ptcolor:#00ff00}
</style>
这个前面带有 . 的 tab 就是一个css 类。引用的时候就得这样:
<div class="tab">这里面的内容就会应用 .tab 类</div>。当然也可以
<span class="tab">这也是一样的效果。</span>
就是任何的标签都可以引用这个 .tab 类。
如果定义不在本网页中的话,那就是使用了外部链接。就是说有一个外部的css文件。那样在使用的时候就这样:<link rel="stylesheet" type="text/css" href="abc.css">(放在<head></head>之间)。引用的时候还是用class="tab"。
