在鼠标浮动在元素上后,元素的样式改变的情况下,:hover选择器是一种很好的选择。接下来看看:hover的相关定义及用法。

:hover选择器用于选择鼠标指针浮动在上面的元素。

注意:

1.一开始我以为:hover选择器只可用于链接上,但事实上,它竟可以用于所有的元素。
2.在CSS定义中,:hover必须位于:link和:visited之后(如果存在的话),这样才可以生效。

下面来看一段使用的代码。

<!DOCTYPE html><html><head>    <meta charset="utf-8"/>    <style>        p:hover{color:red;}        /*第二个注意事项,可以改变a:hover的位置来验证*/        a:link    {color:blue;}        a:visited {color:blue;}        a:hover   {color:red;}        a:active  {color:yellow;}    </style><head><body>    <p>当鼠标滑过时,字体变红</p>    <a href="http://segmentfault.com/blog/sexyMustaches">sexyMustaches</a></body></html>
