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%, and 100% by default. Modify those values as you need to generate different utilities here.

Width 25% Width 50% Width 75% Width 100% <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> Height 25% Height 50% Height 75% Height 100% <div style="height: 100px; background-color: rgba(255,0,0,0.1);"> <div class="h-25 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 25%</div> <div class="h-50 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 50%</div> <div class="h-75 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 75%</div> <div class="h-100 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 100%</div> </div>

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

Max-width 100% <img class="mw-100" src="..." alt="Max-width 100%"> Max-height 100% <div style="height: 100px; background-color: rgba(255,0,0,0.1);"> <div class="mh-100" style="width: 100px; height: 200px; background-color: rgba(0,0,255,0.1);">Max-height 100%</div> </div>
