以下代码用于其中一个类。我们被要求为我们的一个项目制作一个网站。我们的教授总是希望在我们交作业之前通过一个验证器。我得到了这个错误，错误:偏离结束标签HTML。我不知道问题出在哪里。网站工作正常，但验证器告诉我有一个问题。如果您能帮助解决这个问题，我将不胜感激。

如果一个标签没有像段落那样的开始和结束标签，例如:
<p>. .</p>
那么它应该自闭:
<Img src .... />
因此，我建议在meta、style、img和br元素的尖括号前添加正斜杠。
请尝试这样做，看看它是否仍然无法验证
XHTML比HTML更严格，要求所有打开的标记必须关闭，即使它们不是容器标记。因此，非容器标记以/>结尾。例如，换行的标记是<br />。
