Frequently Asked Questions

CSS Flexbox (Flexible Box Layout) is a CSS layout model that makes it easy to align and distribute space among items in a container. It works in one dimension - either as a row or a column - and handles dynamic sizing, spacing, and alignment without floats or positioning hacks.

Use the visual controls to set container properties like flex-direction, justify-content, align-items, flex-wrap, and gap. Add or remove child items and adjust their individual flex-grow, flex-shrink, and flex-basis values. The live preview updates instantly and the generated CSS is ready to copy into your project.

Yes. The generator outputs clean, standards-compliant CSS that works in all modern browsers. Flexbox has over 99% browser support globally, so the generated code is safe for production use without any vendor prefixes.

Flexbox is one-dimensional - it works in a single row or column. CSS Grid is two-dimensional - it works in rows and columns simultaneously. Use Flexbox for component-level layouts (navbars, cards, centering) and Grid for page-level layouts (full-page grids, dashboards).

Yes. The visual preview updates in real time as you change properties, so you can see exactly what each flexbox property does. Try changing flex-direction from row to column, or experiment with justify-content values to understand how items are distributed along the main axis.

Set justify-content to 'center' and align-items to 'center' on the container. This centers child elements both horizontally and vertically. You can do this in the generator with two clicks and copy the resulting CSS code.

The generator outputs the core flexbox CSS properties. Flexbox is inherently responsive - items wrap and resize based on available space when you enable flex-wrap. You can add your own media queries to the generated code for breakpoint-specific adjustments.

No. The tool runs entirely in your browser. There is nothing to install, no account to create, and no signup required. Just open the page and start building your flexbox layout visually.
