How correct and valid is it to put the title inside the P tag?

Question

css

The customer brought a non-standard template where the title tag is inside the text, this is such an idea, this is how it should look like!
How true is this?

Answer 1

I think the validator won't approve headings inside paragraphs, but the browser as a whole doesn't care at all. If you're interested in "sane logic" (or a validator), wrap this header in a span tag and problem solved...

Answer 2

Not only is it not valid, you can’t physically push it inside - browsers won’t allow it h1, h2 .... pBut did you give up on this one p?
