Add HTML heading to classic grid

Hi Mr. Andrei Strekozov,

As far as I checked, the post title of classic grid does not have heading tag option (h2, h3, h4 ...) so it is not good for SEO. Please update the heading tag feature for post title in classic post grid, simple grid and other grids.

Besides, I cannot edit the gap between cards in classic grid to make it suitable to my website. Please add this feature too.

Thank you very much
