Easily make an element as wide or as tall (relative to its parent) with our width and height utilities.

Width and height utilities

Width and height utilities are generated from the $sizes Sass map in _variables.scss. Includes support for 25%, 50%, 75%, and 100% by default. Modify those values as you need to generate different utilities here.

Width 25%
Width 50%
Width 75%
Width 100%
Width auto
Width 75% on large devices and 100% on small ones
