What is CSS Flexbox?

CSS Flexbox (Flexible Box Layout) is a one-dimensional layout method for arranging items in rows or columns. It provides an efficient way to distribute space and align content, even when sizes are unknown or dynamic. Flexbox is essential for modern responsive web design.

Key Flexbox Properties

  • flex-direction: Defines the main axis (row or column)
  • justify-content: Aligns items along the main axis
  • align-items: Aligns items along the cross axis
  • flex-wrap: Controls whether items wrap to new lines
  • gap: Sets spacing between flex items

Common Use Cases

  • Navigation bars and menus
  • Card layouts and galleries
  • Centering content vertically and horizontally
  • Responsive grid alternatives
  • Form layouts and button groups

Frequently Asked Questions

When should I use Flexbox vs Grid?

Use Flexbox for one-dimensional layouts (rows or columns). Use CSS Grid for two-dimensional layouts (rows and columns together). They complement each other and can be used together.

Is Flexbox supported in all browsers?

Yes, Flexbox is fully supported in all modern browsers. For older browsers (IE10-11), you may need vendor prefixes, but modern browsers don't require them.
