Utilities for setting the minimum block size of an element.

Examples

Basic example

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

min-block-96

min-block-80

min-block-64

min-block-48

min-block-40

min-block-32

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

Using a percentage

Use min-block-full or min-block-<fraction> utilities like min-block-1/2, and min-block-2/5 to give an element a percentage-based minimum block size:

min-block-full

min-block-9/10

min-block-3/4

min-block-1/2

min-block-1/3

<div class="min-block-full ...">min-block-full</div><div class="min-block-9/10 ...">min-block-9/10</div><div class="min-block-3/4 ...">min-block-3/4</div><div class="min-block-1/2 ...">min-block-1/2</div><div class="min-block-1/3 ...">min-block-1/3</div>

Using a custom value

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

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

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

<div class="min-block-(--my-min-block-size) ...">  <!-- ... --></div>

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

Responsive design

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

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

Learn more about using variants in the variants documentation.

Customizing your theme

The min-block-<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.
