CSS Flexbox (Flexible Box Layout) is a CSS layout model that makes it easy to design flexible, responsive layouts. It distributes space among items in a container and handles alignment, even when item sizes are unknown or dynamic.

How does this Flexbox Playground work?

Simply adjust the container properties (direction, wrap, alignment, gap) and item properties (grow, shrink, basis, order) using the visual controls. The preview updates in real-time. When you're happy with the layout, click 'Copy CSS' to get the code.

Is my data sent to any server?

No. Everything runs 100% in your browser. No data is sent anywhere — your layout configurations stay completely private on your device.

Can I customize individual flex items?

Yes! Click on any item in the preview or use the item controls to set flex-grow, flex-shrink, flex-basis, align-self, and order for each individual item.
