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.
