I have a layout which I wont the user to be able to scale depending on there screen size (so things are not tiny in 4k for example). So I have set my footer, sidebar and header etc, heights to the rem unit.
But when I set the font size on the body tag it has no affect on the heights. It affects all the text but the layout stays the same in various browsers.
Setting the units to the em instead of rem fixed this but I was curious why rem didn't work.
Thanks in advance
