Grid vs flexbox in CSS - When to Use Which

The Big Idea

Discover how CSS Grid and Flexbox save you hours of frustrating layout work!

The Scenario

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

The Problem

If you want to add or move a photo, you must erase and redraw many marks. It takes a lot of time and mistakes happen easily.

The Solution

CSS Grid and Flexbox let the browser do the arranging for you. You just say how you want things lined up or spaced, and it adjusts automatically.

Before vs After

✗ Before

div { position: absolute; top: 10px; left: 10px; } div:nth-child(2) { top: 10px; left: 110px; }

✓ After

.container { display: grid; grid-template-columns: repeat(3, 1fr); gap: 1rem; }

What It Enables

You can create flexible, neat layouts that adapt to screen sizes without rewriting positions for every item.

Real Life Example

Building a photo gallery that looks good on phones and desktops without moving each photo manually.
