停止链接的 :before 内容被应用于链接的规则加下划线 [英] Stop link's :before content from being underlined by rule applied to the link

问题描述

我有一个文本链接，当悬停时它带有下划线.我正在使用以下代码在链接的开头添加 > 符号:

.box.blueb a { 颜色:#0098aa;}.box.blueb a:hover { 文字装饰:下划线；}.box.blueb a:before { content: "> ";}.box.blueb a:before:hover { 文字装饰:无；}

但是当链接悬停时，我不希望 > 符号带有下划线.我如何实现这一目标?

您需要在 a 中的文本周围包裹一个 span:

<a href="#"><span>你好</span></a>

然后将您的 CSS 更改为:

.box.blueb a { 颜色:#0098aa;文字装饰:无；}.box.blueb a:hover >span { 文字装饰:下划线；}.box.blueb a:before { content: "> ";}

.box.blueb a:before:hover { text-decoration: none;} 不起作用，因为当您在元素(a)上设置 text-decoration: underline 时，你不能在后代上删除它(:before).

I have a text link that is underlined when hovered. I'm adding at the beginning of the link a > symbol using the following code:

.box.blueb a { color: #0098aa; }
.box.blueb a:hover { text-decoration: underline; }
.box.blueb a:before { content: "> "; }
.box.blueb a:before:hover { text-decoration: none; }

But what I don't want the > symbol underlined when the link is hovered. How do I achieve this?

You need to wrap a span around the text inside the a:

<div class="box blueb">
    <a href="#"><span>Hello</span></a>
</div>

And then change your CSS to this:

.box.blueb a { color: #0098aa; text-decoration: none; }
.box.blueb a:hover > span { text-decoration: underline; }
.box.blueb a:before { content: "> "; }

.box.blueb a:before:hover { text-decoration: none; } doesn't work because when you set text-decoration: underline on an element (the a), you can't then remove it on a descendant (:before).
