我已经从w3schools的tryit中复制并粘贴了代码,该代码使您可以使用超链接跳转到网站的任何部分,网址为:http://www.w3schools.com/html/tryit.asp?filename=tryhtml_link_locations。当我单击链接“第4章”时,它跳到了第2章,当我单击顶部div中的“关于我们”时,它转到了同一位置。即使我尝试跳至文档的不同部分,它仍会跳至同一部分。为什么是这样?
编辑:上面似乎工作正常,当我跳到一个标题时,它隐藏在顶部的栏后面。有什么方法可以使其跳到顶部栏下方的位置吗?
谢谢
最佳答案
关于ID,您无需将其放在标题内的<a>
上。只需使用此:
<h2 id="C4">Chapter 4</h2>
关于清除固定标头,以下是有关此问题的一些方便文章:

关于跳到第二章的链接,可能取决于浏览器窗口的高度。它只能在内容允许的范围内下降。如果使用
:target
,您仍然会看到第4章标题为目标。例如#C4:target {background: red;}
