简单问题:如何使用Bootstrap垂直对齐col中的col?例如这里(我想要垂直对齐child1a和child1b):
HTML
<div class="col-lg-12">
<div class="col-lg-6 col-md-6 col-12 child1">
<div class="col-12 child1a">Child content 1a</div>
<div class="col-12 child1b">Child content 1b</div>
</div>
<div class="col-lg-6 col-md-6 col-12 child2">
Child content 2<br>
Child content 2<br>
Child content 2<br>
Child content 2<br>
Child content 2<br>
</div>
</div>
更新
一些 CSS:
.col-lg-12{
top:40px;
bottom:0px;
border:4px solid green;
}
.child1a, .child1b{
border:4px solid black;
display:inline-block !important;
}
.child1{
border:4px solid blue;
height:300px;
display:table-cell !important;
vertical-align:middle;
}
.child2{
border:4px solid red;
}
