css伪类中的:target的使用_html/css_WEB-ITnose

Jun 24, 2016 am 11:29 AM

之前 :target伪类,我们已经接触过了. :target是css中伪类,主要是应用在url中的#链接,以及匹配对应的id名称.例如下面的例子:

代码名称

http://www.wutongwei.com/#home
Copy after login

对应的home 的结构为

代码名称

this is target

这种状态,我们可以通过CSS来体现他的效果.

代码名称

:target{

color:#ff6600;

}

这时候,当浏览这个链接的时候,就会将对应的有id的元素设置他的文字颜色为 #ff6600;

一个页面当然可以有多个target的目标,这时候,这个伪类的样式就适用所有的target元素,如果我们只是改变某个target的话.

这时候我们最好是在CSS上做好选择器的处理.比如

代码名称

this is target

this is another target

CSS上则使用:

代码名称

#home:target{

color:#ff6600;

}

这时候,当浏览http://www.wutongwei.com/#second的时候就不会应用伪类的CSS样式了.

target伪类使用经验:

1. 在在页面上做跳转时,要显示某种状态.

2. 有必要使用这个状态的元素.

3. 接受浏览器的history.

像target这种行为,我们可以在页面上的章节跳转或者评论第跳转等目标跳转.

或者使用在我们常说的tabs上使用.之前我们通常是使用JS来完成tabs的操作.现在可以通过这个伪类来实现.还有就是菜单都可以用这个来实现,等等.
