How can I remove the outline around hyperlinks images?
提问by Wasim Shaikh
When we use Text Replacement using CSS and give a negative test-indent i.e. text-indent:-9999px. Then when we click on that link the Dotted line appears like in the sample image below. What's the solution for this?

Please note that the focus styles are there for a reason: if you decide to remove them, people who navigate via the keyboard only don't know what's in focus anymore, so you're hurting the accessibility of your website.
请注意，焦点样式的存在是有原因的：如果您决定删除它们，那么通过键盘导航的人将不再知道焦点是什么，因此您会损害网站的可访问性。
(Keeping them in place also helps power users that don't like to use their mouse)
（将它们固定到位也有助于不喜欢使用鼠标的高级用户）

There is the same border effect in Firefoxand Internet Explorer (IE), it becomes visible when you click on some link.
在Firefox和Internet Explorer (IE) 中有相同的边框效果，当您单击某个链接时它会变得可见。
This code will fix just IE:
此代码将仅修复 IE：
a:active { outline: none; }.
And this one will fix both Firefox and IE:
这将修复 Firefox 和 IE：
:active, :focus { outline: none; -moz-outline-style: none; }
Last code should be added into your stylesheet, if you would like to remove the link borders from your site.
如果您想从站点中删除链接边框，应将最后的代码添加到您的样式表中。

If you would like to support Firefox 3.6.8 but not Firefox 4... Clicking down on an input type=image can produce a dotted outline as well, to remove it in the old versions of firefox the following will do the trick:
如果你想支持 Firefox 3.6.8 但不支持 Firefox 4...点击输入 type=image 也可以产生一个虚线轮廓，要在旧版本的 Firefox 中删除它，以下将起作用：
input::-moz-focus-inner {
border: 0;
}
IE 9 doesn't allow in some cases to remove the dotted outline around links unless you include this meta tag between and in your pages:
IE 9 在某些情况下不允许删除链接周围的虚线轮廓，除非您在页面之间和页面中包含此元标记：
<meta http-equiv="X-UA-Compatible" content="IE=9" />
