例如,请参阅下面的代码,当我将浏览器的大小调整到非常小的宽度时,网格将会折叠,因此两个按钮组和文本在垂直方向上对齐,并且它们之间没有空格,我该如何添加一些空间?
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
<div class="col-md-2">
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
<div class="col-md-2">
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
<div class="col-md-8">
asdf
</div>
</div>

您最初可以设置margin-bottom
,也可以在媒体中将其更改为:
@media (max-width: 991px){
.col-margin{
margin-bottom: 10px;
}
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
<div class="col-md-2 col-margin">
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
<div class="col-md-2 col-margin">
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
</div>
<div class="col-md-8 col-margin">
asdf
</div>
</div>

您可以将.classname >[class*='col-']
与行结合使用,为该行内的列添加空格或规则。
@media (max-width: 991px) {
.col-space >[class*='col-'] {
margin-bottom: 10px;
}
}
