Flexbox & Grid Playground
Visual flexbox and CSS grid playground with exportable CSS.
About this tool
Arrange items with live CSS flexbox and grid properties. Toggle direction, alignment, gap, and template columns to see layout behavior before writing component code.
Copy the generated CSS into your project or debug a tricky alignment issue from a reduced test case.
All layout preview happens client-side.
How to use
- Switch between Flexbox and CSS Grid modes.
- Tweak direction, alignment, wrapping, gaps, columns, and rows visually.
- Preview how children redistribute as you change controls.
- Export the CSS rules and adapt class names to your layout.
Example
Toolbar flex row
Input
display:flex; direction:row; justify:space-between; align:center; gap:1rem
Output
.element {
display: flex;
flex-direction: row;
justify-content: space-between;
align-items: center;
gap: 1rem;
}Limitations
- Playground children are placeholders — real content intrinsic sizes will change wrapping.
- Subgrid, masonry, and container query variants are not covered.
- Exported CSS is a starting point; responsive breakpoints still need media queries.
