I'm trying to build a mobile only HTML page which splits the screen into tiles.
I have 5 tiles per row, so the tile width is determined as 20% of the screen. I would like the height to be the same - 20% of the screen width. Note that's hight = 20% of device width, not height. The page will scroll downward if there are more tiles.
Is there any way to do this with CSS? I'd rather not have to javascript unless I have to.
