The Big Idea

Discover how to make your web layouts arrange themselves perfectly without extra effort!

The Scenario

Imagine you are arranging photos on a wall. You try to place each photo by measuring and marking exact spots manually.

The Solution

Grid auto-flow and placement let the browser automatically arrange items in neat rows or columns. You just tell it the rules, and it handles the layout perfectly.

<div style="position:absolute; top:10px; left:110px;">Photo 2</div>

✓ After

<div class="grid grid-cols-3 grid-flow-row gap-4">
  <div>Photo 1</div>
  <div>Photo 2</div>
</div>
