问题描述
我有一个产品类别页面,每行3个产品.我希望每一行的最后一行除外都应有边框底部.这应该没有边框底.最后一行可能包含1个,2个或3个<li>
元素.
I have a product category page with 3 products per row. I want every row to have a border bottom except for the last row. This should have no border bottom. The last row may contain 1, 2, or 3 <li>
elements.
我正在使用的当前代码将border-bottom属性应用于每个第三个<li>
元素,这并不是我想要的.
The current code that I'm using applies the border-bottom property to every 3rd <li>
element, which is not quite what I want.
CSS:
.products li {
width: 33.33333%;
}
.products li:nth-child(3n){
border-bottom: 1px rgba(51, 51, 51, 0.1) solid;
}
.products li:nth-child(2-PREVIOUS-SIBLING-ELEMENTS){
border-bottom: 1px rgba(51, 51, 51, 0.1) solid;
}
HTML:
<ul class="products">
<li>Product</li>
<li>Product</li>
<li>Product</li>
<li>Product</li>
<li>Product</li>
<li>Product</li>
</ul>
推荐答案
我想我明白了.下面的第二个规则集说明了最后一行中任何数量的产品.
I think I figured this out. The second ruleset below accounts for any amount of products on the last row.
.products li:nth-child(3n){
border-bottom: 1px rgba(51, 51, 51, 0.1) solid;
}
.products li:nth-last-child(-n + 3):nth-child(3n + 1),
.products li:nth-last-child(-n + 3):nth-child(3n + 1) ~ li {
border: none;
}
