HOW CRATE ASPECT RATION = 1 IN ROW? OR TURN OF SCROLL IN GRID

I want to create a string that will have two containers inside. At the same time, the ratio of the sides of these containers should always be the same. How to do this without using a grid. The problem with the grid is that if you use it to create one such element that will be full screen wide, there are problems with scrolling in the web version, that is, if I try to scroll the screen and get on the grid, then the grid itself tries to scroll, is it possible to turn it off somehow?
