Frequently Asked Questions

What is CSS Flexbox?▾

CSS Flexbox (Flexible Box Layout) is a CSS layout model that makes it easy to align, distribute, and size items within a container — even when their sizes are unknown or dynamic. It's the go-to solution for one-dimensional layouts (rows or columns) and is supported by all modern browsers.

What Flexbox properties can I configure?▾

This tool lets you configure all major container properties: flex-direction (row, column, reverse), justify-content (start, center, end, space-between, space-around, space-evenly), align-items (stretch, start, center, end, baseline), flex-wrap (nowrap, wrap, wrap-reverse), align-content, and gap.

Does this generate Tailwind classes too?▾

Yes. In addition to standard CSS, the tool generates equivalent Tailwind CSS utility classes for every property you configure. Copy either format with one click.

What are the presets?▾

Quick presets let you jump to common layouts instantly: 'Center Everything' for perfectly centered content, 'Space Between' for navigation-style spacing, 'Column Layout' for vertical stacking, 'Navbar' for horizontal navigation bars, 'Wrap Grid' for responsive grid-like layouts, and 'Sidebar Layout' for two-column designs.

Can I change the number of flex items?▾

Yes. Use the controls to add or remove child items (1-12). Each item is a different color for easy visual identification, and they have varying sizes to demonstrate how Flexbox handles items of different dimensions.

Is this tool free?▾

Yes, completely free with no signup required. All code generation happens in your browser — nothing is sent to any server.
