About this tool
Alignment without guesswork
Flexbox is ideal for centering, distributing space, wrapping items, and aligning controls. Previewing property combinations makes layout behavior easier to understand.
Use Flexbox where it fits
Flexbox is best for one axis at a time. Use CSS Grid when the layout depends on both rows and columns, page regions, or complex two-dimensional placement.
Example usage
Input
Direction row, justify center, align center, gap 16px
Output
display: flex; justify-content: center; align-items: center; gap: 16px;
Practical guide for CSS Flexbox Generator
Best practices
- Use gap for spacing instead of stacking margins on flex children.
- Choose row or column direction based on the main axis of the component.
- Switch to Grid when placement depends on both rows and columns.
Common mistakes
- Using Flexbox for complex page grids where CSS Grid would be clearer.
- Forgetting flex-wrap on layouts that need to survive narrow screens.
- Mixing item margins and container gap until spacing becomes unpredictable.
