CSS Flexbox Generator — Build Flex Layouts Visually
Create pixel-perfect CSS Flexbox layouts with a real-time visual editor. Adjust alignment, direction, and wrapping then copy the exact CSS code.
Why use our CSS Flexbox Generator tool?
CSS Flexbox is the go-to layout model for modern web development, but writing it from memory is error-prone. Which property goes on the container versus the child? Is it justify-content or align-items for vertical centering? Our free CSS Flexbox Generator removes all that guesswork. You set properties using visual toggles and sliders, and the generated CSS updates live in a preview panel. When the layout looks right, you copy the complete, production-ready CSS in one click. It is used by beginners learning Flexbox for the first time, and by senior developers who just want to skip looking up flex-wrap versus flex-flow syntax for the hundredth time.
Key Features
- Real-Time Visual Preview: See your Flexbox layout change live as you adjust flex-direction, justify-content, align-items, gap, and wrapping properties. No guessing, just results.
- Container + Item Control: Control both the flex container properties (direction, wrap, justify, align) and individual flex item properties (flex-grow, flex-shrink, order, align-self) in one interface.
- One-Click Copy: The generated CSS is always clean and minimal. Copy only the container CSS, only the item CSS, or both at once.
Common Use Cases
Learning Flexbox
The visual feedback loop makes it the best way for beginners to understand exactly what each Flexbox property does without reading lengthy documentation.

Debugging Layouts
When a Flexbox layout behaves unexpectedly, reproduce the issue here with fresh markup to isolate whether the problem is in your container or item properties.
