如何更改Bootstrap 4的flexbox网格系统的列顺序?
我的代码:
<div class="contents">
<div class="row row-1">
<div class="col-sm-6">Content Left</div>
<div class="col-sm-6">Content Right</div>
</div>
<div class="row row-2">
<div class="col-sm-6">Content Right</div>
<div class="col-sm-6">Content Left</div>
</div>
<div class="row row-3">
<div class="col-sm-6">Content Left</div>
<div class="col-sm-6">Content Right</div>
</div>
<div class="row row-4">
<div class="col-sm-6">Content Right</div>
<div class="col-sm-6">Content Left</div>
</div>
</div>
我想设置它,以便每个偶数行都会使它的列顺序颠倒过来。 我到目前为止的CSS:
.row:nth-child(2n) .col-sm-6:first-child{
float:right;
}

不需要额外的CSS 。使用flexbox ordering utils ...

更新2018 Bootstrap 4(4.0.0)
<div class="contents">
<div class="row row-1">
<div class="col-sm-6">Content Left</div>
<div class="col-sm-6">Content Right</div>
</div>
<div class="row row-2">
<div class="col-sm-6">Content Right</div>
<div class="col-sm-6 order-first">Content Left</div>
</div>
<div class="row row-3">
<div class="col-sm-6">Content Left</div>
<div class="col-sm-6">Content Right</div>
</div>
<div class="row row-4">
<div class="col-sm-6">Content Right</div>
<div class="col-sm-6 order-first">Content Left</div>
</div>
</div>
排序类现在是order-first
,order-1
,order-2
等......

另一种方法是使用flexbox direction utils ...
<div class="row flex-row-reverse flex-md-row">
<div class="col-6">A</div>
<div class="col-6">B</div>
</div>
