About this tool

IconVault's Flexbox Generator lets you build flex layouts by clicking instead of memorizing properties. Adjust flex-direction, flex-wrap, justify-content, align-items, align-content and gap with controls while a live preview updates instantly, then copy the generated clean CSS. It is free and runs fully in your browser.

Flexbox is the fastest way to center things, build navbars, card rows and responsive stacks, but the property combinations are easy to get wrong. Seeing the layout change as you tweak each control builds intuition far faster than reading spec pages.
