Examples

Basic example

Use utilities like auto-cols-min and auto-cols-max to control the size of implicitly-created grid columns:

<!-- [!code classes:auto-cols-max] -->
<div class="grid auto-cols-max grid-flow-col">
  <div>01</div>
  <div>02</div>
  <div>03</div>
</div>

Using a custom value

Use the auto-cols-[<value>] syntax to set the grid auto columns based on a completely custom value:

<div class="grid grid-flow-col auto-cols-[minmax(0,2fr)] ...">
  <!-- ... -->
</div>

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

<div class="grid grid-flow-col auto-cols-(--my-columns) ...">
  <!-- ... -->
</div>

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

Responsive design

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

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