我正在尝试创建此时间表来向人们介绍涂鸦艺术。我有一个问题，我无法缩短页面长度，这会使我向下滚动至虚无。这是仅包含CSS和HTML的代码。
编辑： 这是关于我的问题的一个Gif文件，我尝试删除了时间轴：3000px，但它仅适用于代码段，不适用于Dreamweaver。我试图同时在Chrome和Firefox上运行

如您所见，我尝试通过在正文和容器中使用max-height来减小页面的高度。但这根本没有用。 预先谢谢你！
答案 0 :(得分：2)
.timeline {
height: 3000px;
}
这是问题所在。我删除了height: 3000px，现在看起来还不错。另外，我认为max-height: 3000px和body中的ul不再需要。

答案 1 :(得分：1)
所以一段时间后，我弄清楚自己是什么问题。 问题是： 1 /。时间轴 这是父母，职位是相对的。我将此最大高度设置为3000px 2 /我为每个#closer设置的高度越来越大，它们也是相对的。 （每个-200px）
由于这两件事，我不小心将身高扩大了
之所以我没有早点注意到这个原因是因为在我的原始文件中，我将＃closer1设置为-400px，将＃closer2设置为-800px。但是，这将我的时间轴总最大高度扩展到超过（3000px）。这就是导致我的页面比以前更长的原因。
是的，当我删除最大高度并将每个#closer更改为-200px时，就可以了
