我正在尝试将50px
移到margin-top: 50px
下方,但#section
与*{ padding:0; margin:0; }
body { width:100%; font-family:"Source Sans Pro" }
#section { height:400px; background-color:#383838; color:White; }
span { font-size:40px; }
.column { width: 300px; border: 2px solid yellow; margin-left:40px; margin-top:50px; }
一起移动。为什么这样以及如何解决?

您可以将padding-top: 50px
应用于#section
而不是margin-top
至.column
从Mozilla文档引用:
如果没有边框,填充,内联内容或间隙将块的边距顶部与其第一个子块的边距顶部分开,或者没有边框,填充,内联内容,高度,最小高度,或max-height将块的边距底部与其最后一个子节点的边缘底部分开,然后这些边距会崩溃。折叠的保证金最终在父母之外。

如果您想使用margin-top
,请将display:block
提供给父div,将display:inline-block
提供给子div。

您应该在小提琴中使用padding-top
#section
,并从小孩中删除margin-top
。由于margin
s会相互折叠,因此最好不要将它用于定位元素。请参考:Margin goes outside div when border is removed
#section {
padding-top: 40px;
...
}
另一种方法是使用相同的代码,但将overflow:auto
添加到#section,如下所示:
#section {
overflow:auto;
...
}
还有另外一种解决方案,就像在父级上使用边框一样,但由于我们使用边距进行定位,所以这些更像黑客。
*{ padding:0; margin:0; }
body { width:100%; font-family:"Source Sans Pro" }
#section { height:400px; background-color:#383838; color:White; padding-top:50px;}
span { font-size:40px; }
.column { width: 300px; border: 2px solid yellow; margin-left:40px; }
