Is it possible to select the last n items with nth-child?(是否可以选择带有 nth-child 的最后 n 个项目?)
问题描述
使用标准列表,我试图选择最后 2 个列表项.我有 An+B
的各种排列,但似乎没有选择最后 2 个:
Using a standard list, I'm trying to select the last 2 list items. I've various permutations of An+B
but nothing seems to select the last 2:
li:nth-child(n+2) {} /* selects from the second onwards */
li:nth-child(n-2) {} /* selects everything */
li:nth-child(-n+2) {} /* selects first two only */
li:nth-child(-n-2) {} /* selects nothing */
我知道像 :nth-last-child()
这样的新 CSS3 选择器,但如果可能的话,我更喜欢在更多浏览器中工作的东西(不要关心 IE特别是).
I'm aware of a new CSS3 selectors like :nth-last-child()
but I'd prefer something that works in a few more browsers if possible (don't care about IE particularly).
推荐答案
这将选择列表的最后两个 iem:
This will select the last two iems of a list:
li:nth-last-child(-n+2) {color:red;}
<ul>
<li>fred</li>
<li>fred</li>
<li>fred</li>
<li>fred</li>
<li>fred</li>
<li>fred</li>
<li>fred</li>
<li>fred</li>
</ul>
