【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!
