Suggested change

	background-color: $white;
	flex-glow: 1;
	background-color: $white;

Without flex-grow, the background color would not stretch to its full height when there is little content.

I can confirm this proposal using flex-grow: 1 fixes the issue and also allow the background-color to cover the entire space when there is less content.
