使用最后一个子选择器

Using the last-child selector(使用最后一个子选择器)

问题描述

我的目标是在最后一个 li 上应用 CSS，但它没有这样做.

My goal is to apply the CSS on the last li, but it doesn't do that.

#refundReasonMenu #nav li:last-child {
    border-bottom: 1px solid #b5b5b5;
}

<div id="refundReasonMenu">
    	<ul id="nav">
    		<li><a id="abc" href="#">abcde</a></li>
    		<li><a id="def" href="#">xyz</a></li>
    	</ul>
    </div>

如何只选择最后一个孩子?

推荐答案

:last-child 伪类仍然不能可靠地跨浏览器使用.特别是，Internet Explorer 版本 <9、Safari <3.2 肯定 不支持，虽然 Internet Explorer 7 和 Safari3.2 做支持:first-child，奇怪.

The :last-child pseudoclass still cannot be reliably used across browsers. In particular, Internet Explorer versions < 9, and Safari < 3.2 definitely don't support it, although Internet Explorer 7 and Safari 3.2 do support :first-child, curiously.

最好的办法是显式地为该项目添加一个 last-child(或类似的)类，并改为应用 li.last-child.

Your best bet is to explicitly add a last-child (or similar) class to that item, and apply li.last-child instead.
