width - Sizing (original) (raw)

Utilities for setting the width of an element.

Examples

Basic example

Use w-<number> utilities like w-24 and w-64 to set an element to a fixed width based on the spacing scale:

w-96

w-80

w-64

w-48

w-40

w-32

w-24

<div class="w-96 ...">w-96</div>

<div class="w-80 ...">w-80</div>

<div class="w-64 ...">w-64</div>

<div class="w-48 ...">w-48</div>

<div class="w-40 ...">w-40</div>

<div class="w-32 ...">w-32</div>

<div class="w-24 ...">w-24</div>

Using a percentage

Use w-full or w-<fraction> utilities like w-1/2 and w-2/5 to give an element a percentage-based width:

w-1/2

w-1/2

w-2/5

w-3/5

w-1/3

w-2/3

w-full

<div class="flex ...">

  <div class="w-1/2 ...">w-1/2</div>

  <div class="w-1/2 ...">w-1/2</div>

</div>

<div class="flex ...">

  <div class="w-2/5 ...">w-2/5</div>

  <div class="w-3/5 ...">w-3/5</div>

</div>

<div class="flex ...">

  <div class="w-1/3 ...">w-1/3</div>

  <div class="w-2/3 ...">w-2/3</div>

</div>

<div class="flex ...">

  <div class="w-1/4 ...">w-1/4</div>

  <div class="w-3/4 ...">w-3/4</div>

</div>

<div class="flex ...">

  <div class="w-1/5 ...">w-1/5</div>

  <div class="w-4/5 ...">w-4/5</div>

</div>

<div class="flex ...">

  <div class="w-1/6 ...">w-1/6</div>

  <div class="w-5/6 ...">w-5/6</div>

</div>

<div class="w-full ...">w-full</div>

Using the container scale

Use utilities like w-sm and w-xl to set an element to a fixed width based on the container scale:

w-xl

w-lg

w-md

w-sm

w-xs

w-2xs

w-3xs

<div class="w-xl ...">w-xl</div>

<div class="w-lg ...">w-lg</div>

<div class="w-md ...">w-md</div>

<div class="w-sm ...">w-sm</div>

<div class="w-xs ...">w-xs</div>

<div class="w-2xs ...">w-2xs</div>

<div class="w-3xs ...">w-3xs</div>

Matching the viewport

Use the w-screen utility to make an element span the entire width of the viewport:

<div class="w-screen">

  <!-- ... -->

</div>

Alternatively, you can match the width of the large, small or dynamic viewports using the w-lvw, w-svw, and w-dvw utilities.

Resetting the width

Use the w-auto utility to remove an element's assigned width under a specific condition, like at a particular breakpoint:

<div class="w-full md:w-auto">

  <!-- ... -->

</div>

Setting both width and height

Use utilities like size-px, size-4, and size-full to set both the width and height of an element at the same time:

size-16

size-20

size-24

size-32

size-40

<div class="size-16 ...">size-16</div>

<div class="size-20 ...">size-20</div>

<div class="size-24 ...">size-24</div>

<div class="size-32 ...">size-32</div>

<div class="size-40 ...">size-40</div>

Using a custom value

Use the w-[<value>] syntax to set the width based on a completely custom value:

<div class="w-[5px] ...">

  <!-- ... -->

</div>

For CSS variables, you can also use the w-(<custom-property>) syntax:

<div class="w-(--my-width) ...">

  <!-- ... -->

</div>

This is just a shorthand for w-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a width utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="w-1/2 md:w-full ...">

  <!-- ... -->

</div>

Learn more about using variants in the variants documentation.

Customizing your theme

The w-<number> and size-<number> utilities are driven by the --spacing theme variable, which can be customized in your own theme:

@theme {

  --spacing: 1px; 

}

Learn more about customizing the spacing scale in the theme variable documentation.
