Grid Auto Columns

​

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>

​

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.

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

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

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

​

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.

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.

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

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