What This CSS Generator Does

This interactive tool lets you visually configure CSS Flexbox and CSS Grid layouts using buttons and sliders. Every change updates the preview instantly and generates the corresponding CSS code. You can switch between Flexbox and Grid modes, adjust alignment axes, gap sizes, and wrap behavior — all without writing a single line of CSS.

Key Benefits

  • Visual-first approach: Adjust alignment, spacing, and direction by clicking buttons — see the result immediately in the live preview panel.
  • Copy-paste code: The generated CSS is clean, readable, and includes only the properties that are actually needed for your configuration.
  • Flexbox + Grid in one tool: Switch between display modes to compare layout techniques and choose the best one for your use case.
  • No dependencies: Everything runs client-side. No frameworks, no build tools — just vanilla JavaScript and CSS.

Frequently Asked Questions

When should I use Flexbox vs CSS Grid?

Flexbox is best for one-dimensional layouts (a single row or column). CSS Grid is better for two-dimensional layouts (rows and columns simultaneously). Use this tool to experiment with both approaches side by side.

Is the generated code production-ready?

Yes. The CSS output uses standard, well-supported properties. You may want to add vendor prefixes for older browser support if needed.
