Working on a mobile portrait orientation…I want to divide the screen into 3 rows, totally 100% in height…so I add 1 section and 3 containers on top of each other.
Now the problem. I want the top and bottom rows to be about 20% height each, and the middle 60%. Kind of like a header that always stays at the top, with a middle, and bottom. All would of course stretch when the device is rotated.
