Why Gap between grid cells in Tailwind? - Purpose & Use Cases

The Big Idea

Discover how a simple gap can transform your grid from messy to perfect in seconds!

The Scenario

Imagine you are creating a photo gallery with many pictures arranged in rows and columns. You want some space between each photo so they don't stick together.

The Problem

If you try to add space by putting margins on each photo, it's tricky. Margins add extra space outside each photo, but the edges of the gallery might get uneven spacing. Also, you have to carefully adjust margins on each side to avoid double spacing between photos.

The Solution

Using the gap property in a grid layout automatically adds equal space between all grid cells. You don't have to worry about margins or uneven edges. Tailwind's gap-x- and gap-y- classes make it easy to control horizontal and vertical gaps.

Before vs After

✗ Before

<div class="grid grid-cols-3">
  <img class="m-2" src="photo1.jpg" />
  <img class="m-2" src="photo2.jpg" />
  <img class="m-2" src="photo3.jpg" />
</div>

✓ After

<div class="grid grid-cols-3 gap-4">
  <img src="photo1.jpg" alt="Photo 1" />
  <img src="photo2.jpg" alt="Photo 2" />
  <img src="photo3.jpg" alt="Photo 3" />
</div>
