FAQ

What is Flexbox?

Flexbox (Flexible Box Layout) is a one-dimensional CSS layout method for arranging items in rows or columns. It excels at distributing space and aligning items within a container.

When should I use Flexbox over CSS Grid?

Use Flexbox for single-direction layouts like navigation bars, card rows, or centering content. Use Grid when you need to control both rows and columns simultaneously.

Can Flexbox handle vertical centering?

Yes, Flexbox makes vertical centering straightforward with align-items: center on the container, solving the classic CSS vertical-centering problem.
