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.

{% example html %}

Width 25%

Width 50%

Width 75%

Width 100%

{% endexample %}

{% example html %}

Height 25%

Height 100%

You can also use max-width: 100%; and max-height: 100%; utilities as needed.
