Wondering whether to use CSS Grid or Flexbox for your next layout? You’re not alone! Both tools are powerful, modern layout engines — but they shine in different scenarios. Understanding when to use Grid vs Flexbox helps you build flexible, clean, and maintainable designs faster. In this MiniCoursey quick guide, you’ll learn what makes Grid and Flexbox different, practical use cases, and how to choose the right one for each job.
What is CSS Grid?
CSS Grid is a two-dimensional layout system. It’s perfect for building full page layouts, complex grids, or aligning items both horizontally and vertically at once.
.container {
display: grid;
grid-template-columns: 1fr 2fr;
gap: 1rem;
}
Grid makes it easy to create rows and columns with precise control over spacing and alignment.
What is Flexbox?
Flexbox is a one-dimensional layout system — it works in either a row or a column at a time. It’s great for aligning items along a single axis and distributing space within a container.
.nav {
display: flex;
justify-content: space-between;
align-items: center;
}
Flexbox is perfect for nav bars, buttons, or any list of items that flow in a single line.
When to Use Each
- Use Grid for full-page layouts, cards, or complex grids with rows and columns.
- Use Flexbox for aligning items in a row or column, or for smaller UI components.
- Combine them! Many modern layouts use Grid for structure and Flexbox for smaller parts inside.
💡 Pro Tip: Use browser dev tools’ Grid and Flex inspectors to debug layouts quickly.
⚠️ Common Mistake: Don’t force Flexbox to do complex 2D layouts — that’s what Grid is for!
FAQ
Q: Can I nest Flexbox inside Grid?
A: Absolutely! It’s a common pattern — Grid for big layout, Flex for content alignment.
Q: Is one better for performance?
A: Both are highly optimized — use whichever fits your structure best.
