You can do this using the “columns” feature. For the head area use a block at 100%. For the body and side, use a “column” block with two columns at a 9:3 ratio.
@Jonas76 - The head is not a problem, a simple block with 100%.
The problem is the 2 div´s, the main block (blue) and right side bar (green).
The 2 div´s have one thing in common, 100% height, but the side bar has 200px fixed size, so i cannot use columns, because rows cannot have the size determined by the webflow responsive…
@thesergie - The big problem here, is that i have one div (green) with 200px fixed size, and other one with 100% with size. I cannot float 2 div´s with this property.
@Rui_Almeida it’s true sadly you can’t use pure CSS to set one to be pixels and one to be percent and have them work together. I wish they had something like that. I think you can make it work this way - put the sidebar INSIDE of the 100% width block and float it to the right (and set it’s width to 200px). If you set the sidebar to 100% height, content inside the 100% block should not peak beneath the sidebar (if the sidebar has less content).
