It is semantic. Heading 2 size is not the same thing as <h2>. Wether you call it Heading 2 or Level 2 Heading or whatever, those are just different ways of describing visually the same thing.

In my world, .h2 .heading-2, or anything else describing a scale of type is doing exactly what you are talking about. .h2 !== <h2>. I'm not applying the semantics of one element to another, I'm describing one element as having the 2nd largest size a heading can have. Ya dig?

That’s a self conflicting answer. If the item can semantically be described as the second most important hierarchical header on the page, it belongs in an <h2> tag, ya dig?

Hierarchical size order and semantic order aren't always tied together. Size !== semantic importance.

Size values are presentational. OMG y'all are sucking me back in. ahhhhhh

One thing to keep in mind here, I'm no good at the English language, there very well could be a disconnect between what my brain thinks and what you are reading. :)

What's your native language?

English 😆. I just have dyslexia, so there are challenges.

I was almost forced to take English as a 2nd language in college though because my professors thought I wouldn't pass my Freshman level English requirements. Speaking is no problem for me, but my reading/writing isn't fantastic.

You seem to write perfectly well to me. As for the dyslexia, is it a letter order issue or different? I have issues with language too, but they fall under OCD. For real :)
