height
set height explicitly
Avoid explicitly setting the height of an element to avoid overflow issues.
Specifying a % height is problematic.
% refers to the parent's size.
parent's height is typically determined by the height of its children. This produces a circular definition that the browser canโt resolve, so itโll ignore the declaration.
height: 100%
For percentage-based heights to work, the parent must have an explicitly defined height. ๐ฃ Why doesn't height: 100% working?
