Is it semantically correct to use h2 tag inside summary tag?

Question

I am not sure whether is it correct to have <h2> tag inside <summary> tag.

Whether semantically it is valid to have <h2> or <h1> tag inside <summary> tag?

Answer 1

The semantics would depend on the specific content you had and the context it appears in.

From a validity point of view, the spec says:

Content model:
Phrasing content, optionally intermixed with heading content.

So, it is valid.
