Sizing
Easily make an element as wide or as tall (relative to its parent) with our width and height utilities.
Width classes
Width and height utilities are generated from the $sizes Sass map in assets/include/scss/vendor/bootstrap/_custom.bootstrap.variables.scss. Includes support for 25%, 50%, 75%, and 100% by default. Modify those values as you need to generate different utilities here.

Important
Space does not include all classes, but includes only used classes to reduce the size of CSS files. However, you can add more sizes by adding entries to the $sizes Sass map variable via: assets/include/scss/vendor/bootstrap/_custom.bootstrap.variables.scss.
You can also use max-width: 100%; utility as needed.
