Sizing

Easily make an element as wide or as tall with our width and height utilities.

On this page:



Relative to the parent

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

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

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

PlaceholderMax-width 100%
<svg class="bd-placeholder-img c-mw-100" width="100%" height="100" xmlns="http://www.w3.org/2000/svg" aria-label="Placeholder: Max-width 100%" preserveAspectRatio="xMidYMid slice" role="img"><title>Placeholder</title><rect width="100%" height="100%" fill="#868e96"/><text x="50%" y="50%" fill="#dee2e6" dy=".3em">Max-width 100%</text></svg>
Max-height 100%
<div style="height: 100px; background-color: rgba(255,0,0,.1);">
  <div class="c-mh-100" style="width: 100px; height: 200px; background-color: rgba(0,0,255,.1);">Max-height 100%</div>
</div>

Relative to the viewport

You can also use utilities to set the width and height relative to the viewport.

<div class="c-min-vw-100">Min-width 100vw</div>
<div class="c-min-vh-100">Min-height 100vh</div>
<div class="c-vw-100">Width 100vw</div>
<div class="c-vh-100">Height 100vh</div>
