What is this tool for?

The Flexbox Generator helps with common everyday layouts: navigation bars, card rows, button groups, form sections and flexible content areas. The generated output is designed to be copied into existing CSS files.

Alignment: controls horizontal and vertical distribution inside the container.
Wrapping: creates multi-line layouts when space gets tight.
Item sizing: defines growth, shrinking and basis size of flex items.
Responsive rule: optionally creates a simple mobile adjustment.
