Explain CSS Flexbox vs Grid.

Updated Apr 28, 2026

Short answer

Flexbox is designed for one-dimensional layouts (rows or columns), while Grid is for two-dimensional layouts (rows and columns).

Deep explanation

Flexbox distributes space along a single axis and is great for alignment and distributing free space among items. CSS Grid allows you to define complex layouts with both rows and columns simultaneously, making it ideal for overall page structure.

Real-world example

Using Flexbox for a navigation bar and Grid for a photo gallery.

Common mistakes

  • Trying to force Flexbox to act like a 2D grid using complex calc() and margin logic instead of just using CSS Grid.

Follow-up questions

  • When would you use Grid and Flexbox together?
