Question

我还是个新手，我对这个错误意味着什么感到困惑。

 Line 30, Column 5: document type does not allow element "li" here; missing one of "ul", "ol" start-tag

我一直得到这个错误直到第44行

这个省略了什么意思？

 Line 54, Column 7: end tag for "div" omitted, but OMITTAG NO was specified

下面是我的代码:(谢谢，如果有人可以指导我

Answer 1

您的<br/>代码正在放弃验证。删除它们，或者至少将它们放在合适的元素中。对于其他错误，请正确关闭标记。

Answer 2

对于第一条消息，任何<li>必须是<ul>的子级。对于第二条消息，您打开三个<div>但从未关闭它们。 <br />也无效且多余; <li>将自动断行。您的HTML可以修复如下：

Answer 3

尝试在</ul>之后放置</li>。然后用<div>关闭你的上一个</div> ...我很确定应该这样做。此外，所有中断都是错误的格式化，您可以使用CSS更改这些样式，并且它将更兼容浏览器。

Answer 4

检查底部的结束ul标签。它似乎是<ul>，应该是</ul>（您有一个开始标记而不是结束标记）。

请记住XHTML 1.0严格意味着......严格。

Answer 5

这应该更好地验证。

有两个开放的<ul>代码，没有一个结束标记，3 </div>个缺失，很多<br>的b / w <li>。
