Understanding Your Results

Computes pure CSS grid rules and Tailwind CSS arbitrary classes, and provides an interactive sandbox to test container resizing.

Practical Guidance & Next Steps

Use auto-fit when you want columns to stretch and fill all available row width. Use auto-fill when you want tracks to remain at their fixed minimum width even when empty.

What is this?

A design engineering tool that generates responsive CSS Grid layouts using the auto-fit and minmax() functions.

How does it work?

1. Choose repeat mode (auto-fit vs auto-fill) and set minimum column width. 2. Adjust row/column gaps and item count. 3. Test the responsive container width slider and copy pure CSS or Tailwind CSS code.

Why use it?

Enables completely fluid responsive grid systems without managing fragile breakpoint media queries.

Technical Scope & Calculation Limitations

Assumes standard CSS Grid Level 1 specifications supported by 99% of modern web browsers.

Frequently Asked Questions

`auto-fit` collapses empty tracks to 0px allowing existing items to expand and fill the row, while `auto-fill` preserves empty tracks as open spaces.
