Question

I am trying to figure all the valid HTML5 elements that can be nested inside paragraph elements such that w3 validator doesn’t show any errors. I mean I am trying to figure all tags that can replace the dots in the following code such that w3 validator doesn’t show any errors:

<p>...</p>

Is there such a list available? I tried searching on Google without any luck.

Even if the converse list is available, i.e. elements that can not be nested inside paragraph elements, it is good enough for me.

Answer 1

The HTML5 spec tells us that the <p> element’s content model is phrasing content. Phrasing content is defined by the spec:

3.2.5.1.5 Phrasing content

Phrasing content is the text of the document, as well as elements that
mark up that text at the intra-paragraph level. Runs of phrasing
content form paragraphs.

a (if it contains only phrasing content)

abbr

area (if it is a descendant of a map element)
