Bootstrap Footer Columns堆叠和松开页脚颜色

Question

基本上我做了一个黑色背景的页脚。我有3个Col-4，里面有各种信息。在桌面上它看起来很好，但在移动设备上，列堆栈，我想要的。当它们堆叠时，页脚不会更进一步，因此它下方有一个大的白色部分。我想知道是否有人可以看一看并提出建议。代码可能很乱，因为我是新手。

#footer {
	height: 200px;
	position: absolute;
	bottom: 0;
	background-color: #000000;
	width: 100%;
 
}

<footer>
      <div class="container-fluid">
      <div class="row">
 <div class="col-sm-4 col-md-4">

对于Bootstrap中的移动列，您可以更改

  

＆＃34; COL-SM - *＆＃34;

到你需要的值它只能在小屏幕上工作。

}
