Sizing

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.

Width 25%

Width 50%

Width 75%

Width 100%

Width auto

Copy

<div class="w-25 p-3" style="background-color: #eee;">Width 25%</div>
<div class="w-50 p-3" style="background-color: #eee;">Width 50%</div>
<div class="w-75 p-3" style="background-color: #eee;">Width 75%</div>
<div class="w-100 p-3" style="background-color: #eee;">Width 100%</div>
<div class="w-auto p-3" style="background-color: #eee;">Width auto</div>

<div style="height: 100px; background-color: rgba(255,0,0,0.1);">
