CSS Flexbox Generator
Build a flexbox layout visually - container and item properties both controllable - with a live preview.
Adjust container properties (direction, wrap, alignment) and item properties (grow, shrink, order) - the layout preview updates live.
Container Properties
For a grid-based layout instead of flexbox, see the CSS Grid Generator.
What Is Flexbox?
Flexbox is a one-dimensional CSS layout model - a flex container arranges its direct children (flex items) in a row or column, distributing extra space and alignment according to container and item properties.
Why Use This Tool?
Flexbox properties interact in ways that are hard to predict from memory alone (how justify-content and flex-grow combine, for instance) - a live preview shows the actual result immediately.
How to Use It
- Set container properties: direction, wrap, justify-content, align-items.
- Add items and adjust each one's flex-grow, flex-shrink, and order if needed.
- Copy the generated container and item CSS.
Understanding the Result
The output is split into container properties (applied to the flex parent) and item properties (applied to each flex child) - both are needed together for the full layout.
