Sizing

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

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 50%

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


<div
 
class=
"w-50 p-3"

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

<img
 
src=
"..."
 
class=
"mw-100"
 
alt=

>

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

style=
"width: 100px; height: 200px; background-color: rgba(0,0,255,0.1);"
>
Max-height 100%
</div>

Relative to the viewport

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

<div
 
class=
"min-vw-100"
>
Min-width 100vw
</div>


<div
 
class=
"min-vh-100"
>

</div>


<div
 
class=
"vw-100"
>
Width 100vw
</div>


<div
 
class=
"vh-100"
>
Height 100vh
</div>
