所以我试图设置“内容”类的高度,但它似乎不起作用。我对嵌套 DIV 非常陌生,我已经尝试了我在谷歌搜索中发现的修复程序,但似乎没有任何效果。帮助?

最佳答案

这是因为 .inside div 中定义的 height 属性优先。在这种情况下,要使高度属性在 .content 类中起作用,您必须执行如下操作:

.content
{
height: 200px !important;
}

你可以在JS Bin看到一个Demo:http://jsbin.com/exucek/1/edit

尝试更改 height 属性值以查看它的实时应用。您会看到,当值太小时,会出现滚动条。


如果您对 !important CSS 规则感到好奇,请看这里:
