Frequently Asked Questions
What is CSS Flexbox Generator?
The Flexbox Generator is a visual playground where you configure flex container and item properties and instantly see the result. No more guessing what justify-content: space-between actually looks like. Tweak, preview, copy the CSS.
Key Features
Full control over container properties like flex-direction, wrap, justify-content, align-items, and gap. Per-item controls for order, grow, shrink, basis, and align-self. Layout presets (centered, sidebar, holy grail, navbar, card grid, footer) to get you started in one click.
Common Use Cases
Centering content vertically and horizontally, building navigation bars, creating responsive card grids with wrapping, and constructing classic sidebar layouts. Flexbox handles these patterns elegantly with minimal CSS.
Tips
Start with a preset and tweak from there. Use gap instead of margins between flex items for cleaner code. Remember that flex-wrap: wrap is your friend for responsive designs.
