问题描述
我已经搜索过，但没有提出任何有用的答案，所以请点击：
I've searched and have not come up with any useful answers, so here goes:
HTML5 < header> 如果里面只有一个< hx> 标签，则标签是不必要的？例如，我有以下HTML5标记：
Is an HTML5 <header> tag unnecessary if there is only a single <hx> tag inside it? For instance, I have the following HTML5 markup:
<article>
<header>
<h1>Heading Title</h1>
</header>
...
</article>
从HTML5语义的角度来看，当只有一个<在< header> 内没有别的，是< header> 标记不必要/冗余，我应该这样做：
From an HTML5 semantics point of view, when there is only one <hx> tag inside the <header> and nothing else, is the <header> tag unnecessary/redundant, and should I just do this instead:
<article>
<h1>Heading Title</h1>
...
</article>
推荐答案
从W3C的标题 spec的第一个注释部分<上面提到的 ajp15243 ，重点是我的：
From the first Note section on the W3C's header spec which ajp15243 mentioned above, emphasis mine:
标题元素通常包含节的标题（h1-h6元素），但这不是必需的。 header元素还可用于包装部分的目录，搜索表单或任何相关徽标。
A header element is intended to usually contain the section's heading (an h1–h6 element), but this is not required. The header element can also be used to wrap a section's table of contents, a search form, or any relevant logos.
如果你们所有人< h1>< / h1> ，< header> 标签不是您的文档正确形成和语义正确所必需的。
If all you have is a single (as per your example) <h1></h1>, the <header> tag is not required for your document to be properly-formed and semantically correct.
您可能会发现拥有< header> 元素有助于您稍后使用CSS设置 h1 的样式，但就本例中的HTML而言，您在语义上都很好或没有< header> 。
You might find that having the <header> element as a wrapper aids you in styling the h1 later with CSS, but as far as the HTML alone in this case, you're semantically fine either with or without <header>.
