CSS Grid Generator

Summary

The CSS Grid Generator produces clean, production-ready CSS grid declarations from intuitive controls. Choose your column and row track sizing — equal fractions, fixed pixels, or custom expressions — then set your preferred gap and alignment. The output is a complete `.grid-container` CSS class you can paste directly into any stylesheet.

How it works

1. Set the number of columns and choose a sizing mode: equal fractions (fr), fixed pixel width, or a custom track definition.
2. Optionally define row tracks using the same sizing modes.
3. Adjust column gap and row gap sliders (or enter exact pixel values).
4. Choose justify-items and align-items alignment options for grid children.
5. The generated CSS updates live — click "Copy CSS" to copy it to the clipboard.
6. Paste the CSS into your project stylesheet and apply the class to your container.
