答:悬停不工作

问题描述

HTML

 <table width="100%">
<tr>
    <td width="90%"></td>
    <td><a href="#" id="logout"><strong>Logout</strong></a></td>
 </tr>
</table>

CSS

@charset "utf-8";
/* CSS Document */

#logout {
color:#BBB;
}

a:hover {
color:#FFF;
}

虽然注销的颜色似乎是 css 中给出的颜色，但当我将鼠标放在链接 (to white) 上时颜色不会改变.是什么原因?

Though the color of logout appears to be what is given in the css , the color doesn't change when i place my mouse over the link (to white) . What is the reason ?

我必须说还有其他 css 文件，当鼠标放在它们上面时，它们往往会改变链接的颜色并且它们工作正常.

I must tell there are other css files that tend to change the color of the link when the mouse is placed over them and they work fine.

推荐答案

id 选择器 (#logout) 比类型选择器 (a) 加一个伪类 (:hover)，因此您的第一个规则集将始终 赢得级联.

An id selector (#logout) is more specific then a type selector (a) plus a pseudo-class (:hover), so your first ruleset will always win the cascade.

使用 #logout:hover 代替.
