Quick reference

Class	Description

Basic usage

Sizing implicitly-created grid columns

Use the auto-cols-{size} utilities to control the size of implicitly-created grid columns.

<div class="grid grid-flow-col auto-cols-max">
  <div>01</div>
  <div>02</div>
  <div>03</div>
</div>

Arbitrary values

If you need to use a one-off grid-auto-cols value that doesn't make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="grid grid-flow-row auto-cols-[minmax(0,_2fr)]">
  <!-- ... -->
</div>

Applying conditionally

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:auto-cols-min to apply the auto-cols-min utility at only medium screen sizes and above.

<div class="grid grid-flow-col md:grid-flow-row">
  <!-- ... -->
</div>
