a:active的作用是什么简单介绍:
本章节介绍一下a:active的作用是什么，需要的朋友可以做一下参考。
它的作用是规定链接激活状态下的样式规则。
很多初学者可能对这个"激活状态"不太理解，下面做一下介绍:
所谓的激活状态就是鼠标按键在链接上按下但是还没有松开时的状态。
代码实例如下:
<!DOCTYPE html><html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style>a{ text-decoration:none; }a:link{color:red}a:visited{color:blue}a:hover{color:green}a:active{color:yellow}</style></head><body><a>蚂蚁部落</a></body></html> 上面的代码中，当鼠标按下还没有松开的时候，链接颜色呈现黄色。
更多关于链接伪类选择器的用法可以参阅CSS中a:link、a:visited、a:hover、a:active的用法一章节。
