我的问题是：当我删除html中的评论标签“”时，页面的宽度突然比浏览器窗口宽。你们有任何想法如何解决这个问题吗？我觉得这是一种奇怪的错误。

Answer 1

这是更新的JsFiddle https://jsfiddle.net/4erj4w2p/1/。问题是你的宽度单位 - vw（视口宽度）。它还考虑了滚动条宽度。请参阅：Why does vw include the scrollbar as part of the viewport?

更新了Css：

Answer 2

首先，＃rightBlock中没有高度..添加：

height: 60vh;

然后，当你添加第二部分lowerContainer时，你自动＆＃34;创建一个垂直滚动条。由于您的滚动条，您需要更多的水平空间来显示您的内容，这是因为您拥有水平滚动条。

如果你改为高度= 10vh，你就不会有任何问题。

Answer 3

由于100vw，这提供了额外的宽度。我用100％更新了100vw，它工作正常。请通过更新来检查。

还能告诉我关于vw的事吗？它与px有什么关系吗？或只是一个区域问题？

使用text-align：center时网站的宽度突然溢出;并显示：inline-block;
