Grid Auto Columns

Utilities for controlling the size of implicitly-created grid columns.

Quick reference

Class	Properties
auto-cols-auto	grid-auto-columns: auto;
auto-cols-min	grid-auto-columns: min-content;
auto-cols-max	grid-auto-columns: max-content;
auto-cols-fr	grid-auto-columns: minmax(0, 1fr);

Basic usage

Sizing implicitly-created grid columns

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


1. <div class="grid grid-flow-col auto-cols-max">
2. <div>01</div>
3. <div>02</div>
4. <div>03</div>
5. </div>

Applying conditionally

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:auto-cols-min to only apply the auto-cols-min utility on hover.


1. <div class="grid grid-flow-col auto-cols-max hover:auto-cols-min">
2. <!-- ... -->
3. </div>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

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.


1. <div class="grid grid-flow-col auto-cols-max md:auto-cols-min">
2. <!-- ... -->
3. </div>

Using custom values

Customizing your theme

By default, Tailwind includes four general purpose grid-auto-columns utilities. You can customize these values by editing theme.gridAutoColumns or theme.extend.gridAutoColumns in your tailwind.config.js file.

tailwind.config.js


1. module.exports = {  theme: {    extend: {      gridAutoColumns: {        '2fr': 'minmax(0, 2fr)',      }    }  }}

Learn more about customizing the default theme in the theme customization documentation.

Arbitrary values

If you need to use a one-off grid-auto-columns 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.


1. <div class="auto-cols-[minmax(0,_2fr)]">
2. <!-- ... -->
3. </div>

Learn more about arbitrary value support in the arbitrary values documentation.
