Is <p> semantically correct within an <li> element
提问by Michelle
I'm marking up a series of knowledge base how-to type articles which have a series of steps and associated screenshots. In the past I have always wrapped text within a list item within paragraph tags but I'm wondering if this is semantically correct in this case or if I should be using a heading tag (or even nothing). I'm tempted to mark it up as follows:
我正在标记一系列知识库如何键入文章，其中包含一系列步骤和相关的屏幕截图。过去，我总是将文本包裹在段落标签内的列表项中，但我想知道在这种情况下这在语义上是否正确，或者我是否应该使用标题标签（甚至什么都不使用）。我很想将其标记如下：
<ol class="kbarticle">
<li>
<p>Download the Windows client software <a href="">here</a>.</p>
<a href="#screenshot1"><img src="screen1.jpg" alt="Step 1" /></a>
</li>
<li>
<p>Double click the downloaded file and click "Next" to continue.</p>
<a href="#screenshot2"><img src="screen2.jpg" alt="Step 2" /></a>
</li>
<ol>
Additionally, if there are any HTML5 elements which would be more semantically correct, I'd love to know.
此外，如果有任何 HTML5 元素在语义上更正确，我很想知道。

Here's one way you could mark it up using <figure>:
这是您可以使用<figure>以下标记的一种方法：
<ol class="kbarticle">
<li>
<figure>
<a href="#screenshot1"><img src="screen1.jpg" alt="Step 1"></a>
<figcaption>
Download the Windows client software <a href="">here</a>.
</figcaption>
</figure>
</li>
<li>
<figure>
<a href="#screenshot2"><img src="screen2.jpg" alt="Step 2"></a>
<figcaption>
Double click the downloaded file and click "Next" to continue.
</figcaption>
</figure>
</li>
</ol>

Yes, it's valid. LI is defined as
是的，它是有效的。LI 定义为
<!ELEMENT LI - O (%flow;)* -- list item -->
and %flowis defined as
并被%flow定义为
<!ENTITY % flow "%block; | %inline;">
and %blocknaturally contains P, as it's a block level element.
并且%block自然包含 P，因为它是块级元素。

I'd say that more often than not, the <p>tags are superfluous and the <li>tags alone are sufficient, but it's a fine call, and I don't think what you're doing is really harmful.
我会说，通常情况下，<p>标签是多余的，<li>仅标签就足够了，但这是一个很好的选择，我认为您所做的并没有真正有害。

According to this answer, li's can contain block or inline elements (from the HTML4 spec).
根据这个答案，li's 可以包含块或内联元素（来自 HTML4 规范）。
