About CSS Flexbox Generator

The CSS Flexbox Generator is a visual playground for building flexbox layouts. Use dropdowns and toggles to set flex-direction, justify-content, align-items, flex-wrap, and gap — and watch the live preview update instantly. Then copy the generated CSS for both the container and items.

Flexbox is the backbone of modern CSS layouts, but memorizing all the property values and understanding how they interact takes practice. This visual tool helps you learn and build faster by making the relationships between properties immediately visible.

Useful for both learning flexbox and quickly finding the right combination of properties for a layout.
