The only difference is in the header.
1) On the homepage, the header for example with a height of 300px with one background color, logo,search form, profile.
2) On the other pages the header for example with a height of 100px with a different background, logo, etc on the spot.
How to make it work correctly? To change only the header?
While I had the idea with the tag: available main. Is there anywhere else?
