There was such question, while I was learning to write, everyone always said that the height of the block or wrap the whole section was better not to ask (supposedly to let the unit starts from the content and then ask padenge), since adaptive there's a chance this fall, but recently one foreign movie on bootstrap saw that the coder insolently prescribe all units height in rem (no matter the wrapper it for sexii, button, wrapper pictures, etc.), starting from the body specified in pixels. Rem once more tolerate refers to adaptive? Or is there any trick to register rem whole - blocks, fonts, indentation, etc
