CSS Grid & Flexbox Layout Generator Guide

CSS Grid and Flexbox are the two most powerful layout systems in modern web design. CSS Grid excels at two-dimensional layouts with rows and columns, while Flexbox provides flexible one-dimensional alignment along a single axis.

Grid: display: grid; | Flexbox: display: flex;

Use this tool to experiment with different configurations. Adjust columns, rows, gaps, and alignment controls visually, then copy the generated CSS directly into your project. All processing happens client-side with no data sent to any server.

Frequently Asked Questions (FAQ)

Q: When should I use CSS Grid instead of Flexbox?

A: Use CSS Grid for two-dimensional layouts where you need control over both rows and columns simultaneously. Use Flexbox for one-dimensional layouts where items flow along a single axis, such as navigation bars or centering content.

Q: Can I use the generated CSS in production websites?

A: Yes. The generated CSS uses standard CSS Grid and Flexbox properties that are supported in all modern browsers including Chrome, Firefox, Safari, and Edge. No vendor prefixes are required for current browser versions.

Q: What does the custom grid template column mean?

A: It allows you to define custom column widths using CSS units like 1fr 2fr 1fr for proportional widths, 200px auto 1fr for mixed units, or any valid CSS grid-template-columns value. This overrides the equal-width setting.

Q: Is my layout data saved or transmitted anywhere?

A: No. All CSS generation and preview rendering happens entirely within your browser using vanilla JavaScript. No data is transmitted to any server, and no cookies are used.
