Examples

Basic example

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

min-w-80
min-w-64
min-w-48
min-w-40
min-w-32
min-w-24
<div class="w-20 ...">  <div class="min-w-80 ...">min-w-80</div>  <div class="min-w-64 ...">min-w-64</div>  <div class="min-w-48 ...">min-w-48</div>  <div class="min-w-40 ...">min-w-40</div>  <div class="min-w-32 ...">min-w-32</div>  <div class="min-w-24 ...">min-w-24</div></div>

Using a percentage

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

min-w-1/3
w-full
<div class="flex ...">  <div class="min-w-3/4 ...">min-w-3/4</div>  <div class="w-full ...">w-full</div></div>

Using the container scale

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

min-w-xs
min-w-2xs
min-w-3xs
<div class="w-40 ...">  <div class="min-w-lg ...">min-w-lg</div>  <div class="min-w-md ...">min-w-md</div>  <div class="min-w-sm ...">min-w-sm</div>  <div class="min-w-xs ...">min-w-xs</div>  <div class="min-w-2xs ...">min-w-2xs</div>  <div class="min-w-3xs ...">min-w-3xs</div></div>

Using a custom value

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

<div class="min-w-[220px] ...">  <!-- ... --></div>

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

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

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

Responsive design

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

<div class="w-24 min-w-full md:min-w-0 ...">  <!-- ... --></div>

Learn more about using variants in the variants documentation.

Customizing your theme

The min-w-<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.
