Flexbox (Flexible Box Layout) is a one-dimensional CSS layout model that distributes space among items in a container.

What is the main axis vs cross axis?

The main axis is determined by flex-direction (row=horizontal, column=vertical). Justify-content aligns along main axis, while align-items aligns along cross axis.

Can I export both CSS and Tailwind?

Yes! The playground automatically derives both pure CSS declarations and modern Tailwind classes.

Does flex-wrap support multi-line wrapping?

Yes, switch flexWrap to "wrap" to see items gracefully wrap onto next lines when container space diminishes.

Is it mobile responsive?

Yes, the playground is fully responsive and touch-friendly.
