Review paddings & margins

@KateNaumenko Please, add some screenshots / pages where we have this issue

@katatsu12 I meant review spaces for all pages and bring them to the same standard. now the distances are mostly in relative units and simply of different sizes: somewhere in vh, somewhere in vw. When changing the screen, it does not always look good. Especially since the requests for max-width 1550px will be deleted, all this needs to be finalized. Examples in screenshots
