【标签选择器】

一个完整的HTML页面是有很多不同的标签组成，而标签选择器，则是决定哪些标签采用相应的CSS样式，(在大环境中你可能出于不同的位置，但是不管怎么样，你总是穿着同一套衣服，这件衣服就是由标签选择器事先给你限定好的，不管走到哪里都是这身衣服)比如，在style.css文件中对p标签样式的声明如下：

p{font-size:12px;background:#900;color:090;}

[/quote]则页面中所有p标签的背景都是#900(红色)，文字大小均是12px，颜色为#090(绿色)，这在后期维护中，如果想改变整个网站中p标签背景的颜色，只需要修改background属性就可以了，就这么容易！
