在< p>内嵌入块级元素标签...对错还是错？ [英] Nesting block level elements inside the <p> tag... right or wrong?

问题描述

在语法和语义上是否正确嵌套< p> 中的任何其他块级别元素< div> $ c>标记。

如果没有，那么可以使用< span style =display：block> c > p 在所有HTML标准中无效。此外，当使用合格的HTML解析器时，不可能在< p> < div> c>，因为开头< div> 标签将自动关闭< p> 元素。

语义上，正确的选择取决于您标记的内容。您将需要至少显示一个示例完整段落以及可能的周围内容，以确保提供足够的信息，以确定正确的语义标记。

但是，由于< div> 和< span> 都是语义自由的，如果你确定< p> 标签的内容真正形成一个段落，并且< span style = display：block> 获得您所寻求的表现效果，那么这是有效的HTML，将是一个完全合适的解决方案。

Is it syntactically and semantically correct to nest <div> or any other block level element inside the <p> tag. I am talking about HTML4 Transitional DTD.

If not then is it OK to instead use <span style="display: block"> instead?

解决方案

Syntactically, a div inside a p is invalid in all standards of HTML. Moreover, when using a conforming HTML parser, it is impossible to place a <div> element inside a <p> in the DOM because the opening <div> tag will automatically close the <p> element.

Semantically, the correct choice depends on the content that you are marking up. You will need to show at least a sample full paragraph and possibly the content surrounding it to be sure of providing sufficient information for the correct semantic mark-up to be determined.

However, given that both <div> and <span> are semantics free, and that CSS in no way can ever change that, if you are certain that the contents of the <p> tag truly form a paragraph, and that <span style="display: block"> gets you the presentational effect that you are seeking, then that is valid HTML and would be a wholly appropriate solution.
