H1、H2、H3、H4、H5、H6 表内的 TH 标签?- HTML [英] H1, H2, H3, H4, H5, H6 inside table TH tags? - HTML
问题描述
我可以在 table TH
标签内使用 H1、H2、H3、H4、H5、H6
吗?- HTML
我尝试使用 w3 验证器进行验证,但它没有验证.我明白了:
元素 h4 不能作为第 th 元素的后代出现.<th><h4>橙色</h4></th>
我用的是HTML5,所以我觉得最好的办法是用
标签放进去.或者这也是一个坏主意?因为它看起来像这样:第一个标题
<h4>第二个标题</h4><h4>第三个标题</h4><p>第一段</p><p>第二个段落</p><p>第三段</p>
我不知道这看起来如何,3 个关闭的标题标签,中间没有任何文本或段落.
HTML living标准明确禁止这样做.th
元素 内容模型是如下(强调):
流内容,但没有页眉、页脚、分节内容或标题内容后代.
标题内容"指的是h1
、h2
等元素,以及 hgroup
元素:
标题内容定义了一个节的标题(无论是明确的使用分段内容元素标记,或由标题暗示内容本身).
h1 h2 h3 h4 h5 h6 hgroup
Can i use H1, H2, H3, H4, H5, H6
inside the table TH
tags? - HTML
I tryed to validate with the w3 validator, but it doesn't validate. I get this:
The element h4 must not appear as a descendant of the th element.
<th><h4>Orange</h4></th>
I use HTML5, so i think that the best idea is to use <div>
to make a table and then put the <H4>
tags in it. Or is this a bad idea too? Because then it looks something like this:
<h4>first title</h4> <h4>second title</h4> <h4>third title</h4>
<p>first parahraph</p> <p>second parahraph</p> <p>third parahraph</p>
And i don't know how this looks, 3 heading tags that close, without any text or paragraphs between that.
The HTML living standard explicity forbids this. The th
element content model is as follows (emphasis added):
Flow content, but with no header, footer, sectioning content, or heading content descendants.
"Heading content" refers to the h1
, h2
etc. elements, as well as the hgroup
element:
Heading content defines the header of a section (whether explicitly marked up using sectioning content elements, or implied by the heading content itself).
h1 h2 h3 h4 h5 h6 hgroup
