Introduction

Column spanning lets a box stretch across multiple columns in a grid. It helps organize content clearly and nicely.

You want a heading to stretch across all columns in a grid.

You need a wide image or button that covers more than one column.

You want to make some content stand out by making it wider than others.

You are building a layout with different sized boxes in a grid.

You want to control how many columns a box uses on different screen sizes.

Syntax

Tailwind

col-span-{n}

// where n is the number of columns to span

Use col-span-{n} to make an element span n columns.

Make sure the parent container uses grid and defines columns with grid-cols-{number}.

Examples

The first box stretches across 2 columns, the second box fills the last column.

Tailwind

<div class="grid grid-cols-3 gap-4">
  <div class="col-span-2 bg-blue-300">Spans 2 columns</div>
  <div class="bg-green-300">Spans 1 column</div>
</div>

The header spans all 4 columns, boxes below each take 1 column.

Tailwind

<div class="grid grid-cols-4 gap-2">
  <div class="col-span-4 bg-red-200">Full width header</div>
  <div class="bg-yellow-200">Box 1</div>
  <div class="bg-yellow-200">Box 2</div>
  <div class="bg-yellow-200">Box 3</div>
  <div class="bg-yellow-200">Box 4</div>
</div>

Two boxes each span 3 columns, splitting the grid in half.

Tailwind

<div class="grid grid-cols-6 gap-3">
  <div class="col-span-3 bg-purple-300">Half width box</div>
  <div class="col-span-3 bg-purple-500">Other half</div>
</div>

Sample Program

This example shows a grid with 4 columns. The header stretches across all columns. Box 2 spans 2 columns, and Box 4 spans 3 columns. Others fill 1 column each.

Important Notes

Column spanning only works inside a grid container.

Use gap-{size} classes to add space between grid items.

You can combine column spanning with responsive prefixes like md:col-span-2 to change span on different screen sizes.

Summary

Use col-span-{n} to make an element cover multiple columns in a grid.

Make sure the parent uses grid and defines columns with grid-cols-{number}.

Column spanning helps create flexible and clear layouts.
