如何去掉可怕的矩形标签

CSS outline property :

<style type = "text/css">
    a {outline:0;} /*this is that dotted line you get when you select an image, I believe you're talking about the outline*/
    a img {border:0;} /*Images in links default to having a blue border, so this could be the source of another annoying rectangle*/
</style>

以下内容被认为是更好的,因为它允许用户仍然通过键盘导航。

a:hover, a:active { outline: none; }
