About CSS Flexbox Generator
This tool helps you build flexbox container styles visually. You can change direction, wrapping, alignment, spacing, and immediately see how items move inside the preview area.
It is useful for building navigation bars, button groups, card rows, centered layouts, responsive blocks, and small UI sections where CSS flexbox is the simplest layout option.
How to use it
- Choose the flex direction and wrapping behavior.
- Adjust justify-content, align-items, align-content, and gap.
- Use the live preview to check how items are placed.
- Copy the generated CSS or paste existing flexbox CSS and parse it.
Tips
- Use justify-content to control the main axis.
- Use align-items to control the cross axis.
- Use flex-wrap: wrap when items need to move to the next line.
- Use gap instead of margins for cleaner spacing between flex items.
