所以我试图设置“内容”类的高度，但它似乎不起作用。我是嵌套 DIV 的菜鸟，我已经尝试了我在谷歌上搜索到的修复程序，但似乎没有任何效果。帮助？

发生这种情况是因为 中height定义的属性.inside div优先。在这种情况下，要使 height 属性在类中起作用，.content您必须执行以下操作：

.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属性值以查看它是否被实时应用。您会看到，当值太小时，会出现滚动条。

!important如果您对该CSS 规则感到好奇，请看这里：

!important 在 CSS 中是什么意思？

您的 CSS 将使用最具体的规则。您已指定高度

.inside div

这比更具体

.content

你也在哪里设置高度。为了让您的 CSS 使用您为 .content 设置的高度，您需要使选择器更具体，如下所示：

.inside div{
       height:450px;
       width:700px;
}
.inside .content {
       height:100px;
       width:300px;
}

这应该够了吧。

你的代码有错误！
替换<div class="content" style=" width:200px;" >为

<div class="content" width=200 >

或更改您的 CSS 代码： 

.content {
       height:200px;
            }
