我已经能够在我的页面上根据接受的答案创建四个大小/形状相等的象限。
所以这一页看起来是这样的：
here
我现在想给象限一些“肘部空间”-一些空白的边缘。我试着给他们使用的类增加边距：
.topleft {
background-color: blue;
margin: 4;
}
.topright {
background-color: red;
margin: 4;
}
.bottomleft {
background-color: green;
margin: 4;
}
.bottomright {
background-color: yellow;
margin: 4;
}
什么也没做；我试着加上填充物：
.topleft {
background-color: blue;
padding: 4;
}
.topright {
background-color: red;
padding: 4;
}
.bottomleft {
background-color: green;
padding: 4;
}
.bottomright {
background-color: yellow;
padding: 4;
}
……这也没什么用。
我需要做些什么来为所有人保留相同的1/4空间，但通过在它们之间添加边距或在它们周围填充来有效地“压扁”它们？

更新
添加填充只是使象限膨胀，而不在象限之间提供任何呼吸空间。它看起来或多或少像是给第一个元素分配了一个“top”属性，进一步向下推。
增加边距（16px）会导致象限在页面上垂直排列-全部在左侧，没有在右侧。这四块是垂直堆放的，每一块都在下一块的上面。
最佳答案
不要向包含引导column类的div添加新类。相反，创建一个子div并将您的样式应用于内部div。
例如：
替换
<div class="row">
<div class="col-md-6 topleft">
...
</div>
</div>
具有
<div class="row">
<div class="col-md-6">
<div class="topleft">
...
</div>
</div>
</div>
这样，您就可以在外部div中控制容器的整体边界，并在内部div中设置容器的样式（添加边距、填充）。
也可以像其他人建议的那样使用px/em单位作为填充/边距。
