我的整个代码是如何设置div的黑白间距？它必须在所有设备上平稳运行
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<body>
<div class="container" style="width:100%">
<div class="row" style="height:33%">
<div class="col-xs-3" style="height:100%;background-color:#003380;"></div>
<div class="col-xs-6 text-center"style="height:100%;background-color:#66a3ff;padding-left: 20px">Top </div>
<div class="col-xs-3 " style="height:100%;background-color:#cce0ff"></div>
</div>
<div class="row" style="height:33%">
<div class="col-xs-3" style="height:100%;background-color:#66a3ff"></div>
</div>
<div class="row" style="height:33%">
<div class="col-xs-3 " style="height:100%;background-color:#cce0ff">left</div>
<div class="col-xs-6 " style="height:100%;background-color:#66a3ff">Center</div>
<div class="col-xs-3 " style="height:100%;background-color:#003380">Right </div>
</div>
</div>
</body>最佳答案
您可以在元素周围换行，从而使换行列的填充提供某种边距/间距。
以下代码是否针对您？
.spacing {
padding: 15px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<body>
<div class="container" style="width:100%">
<div class="row" style="height:33%">
<div class="col-xs-3 spacing">
<div class="col-xs-12" style="height:100%;background-color:#003380;"></div>
</div>
<div class="col-xs-6 spacing">
<div class="col-xs-12 text-center"style="height:100%;background-color:#66a3ff;padding-left: 20px">Top </div>
</div>
<div class="col-xs-3 spacing">
<div class="col-xs-12" style="height:100%;background-color:#cce0ff"></div>
</div>
</div>
<div class="row" style="height:33%">
<div class="col-xs-3 spacing">
<div class="col-xs-12" style="height:100%;background-color:#66a3ff"></div>
</div>
</div>
<div class="row" style="height:33%">
<div class="col-xs-3 spacing">
<div class="col-xs-12" style="height:100%;background-color:#cce0ff">left</div>
</div>
<div class="col-xs-6 spacing">
<div class="col-xs-12" style="height:100%;background-color:#66a3ff">Center</div>
</div>
<div class="col-xs-3 spacing">
<div class="col-xs-12" style="height:100%;background-color:#003380">Right </div>
</div>
</div>
</div>
</body>编辑：
由于您正在寻找各个方向的间距（不仅是左右间距），因此可以向包装中添加一个名为
spacing和以下CSS的额外类：（请参阅更新的代码段）.spacing {
padding: 15px;
}
