Easily make an element as wide or as tall (relative to its parent) with our width and height utilities.
Width and height utilities are generated from the $sizes Sass map in _variables.scss. Includes support for 25%, 50%, 75%, 100%, and auto by default. Modify those values as you need to generate different utilities here.
You can also use max-width: 100%; and max-height: 100%; utilities as needed.
