我在谷歌浏览器上运行了它。我右键单击,选择“Inspect Element”,单击主体部分(因此Chrome应该突出显示整个主体),但它只突出显示
#标题部分。为什么不突出显示整个页面?

因为您忘记了“清除”浮动

<div style="clear: both;"></div>

将其添加到最后一个浮动div的末尾。

它是因为“”。因此,我猜浏览器没有将浮动元素包含到
的正常内容中,因此它们不会突出显示

顺便说一句,它在Firefox的Firebug中的行为是相同的

body {
     margin: auto;
     width: 960px;
     height:750px;
     font-family: Helvetica, sans-serif;
     font-size: 16px;
}

指定主体高度。上述内容应该可以解决您的问题。

难道“检查元素”不关注您单击的精确项目吗?如果它总是检查整个文档,这将是一个完全没有意义的功能。浮动元素会发生这种情况:当你选择父元素时,Chrome通常无法在页面中突出显示它们。@Lewis我们回答了你的问题吗?如果是,请将答案标记为已接受。
