CSS Flexbox Generator

Build a flexbox layout visually and copy the CSS or Tailwind output.
Useful for nav bars, card rows, button groups, and other one-dimensional layouts.

Generate flexbox code when alignment details matter

This CSS Flexbox generator is built for everyday UI layout work: centering controls, spacing items in a row, handling wraps cleanly, and adjusting how individual children grow or shrink inside the same container.

Instead of guessing how a flex setting will behave, you can preview it first, inspect the item-level changes, and copy working output once the layout feels right.

Flexbox FAQ

When should I use Flexbox instead of Grid?

Use Flexbox for one-dimensional layouts where items flow in a single row or column. If you need tighter control across both rows and columns, Grid is usually the better fit.

Can I export both CSS and Tailwind classes?

Yes. The generator outputs plain CSS for the container and items, plus Tailwind classes for the same layout when you want a utility-first version.
