Frequently asked questions

Does this use actual image files for the pattern?
No. Every pattern is built from pure CSS gradients (`linear-gradient` and `radial-gradient`), so there's no image file to host, request, or keep in sync with the pattern's colors.
What pattern styles are available?
Dots, horizontal/vertical stripes, diagonal stripes, a grid, and a checkerboard — each with adjustable size and two colors.
Can I use this as a full-page background?
Yes. Copy the generated CSS and apply it to any element's `background` property, including `body` for a full-page pattern.
Will the pattern scale on different screen sizes?
The tile size stays fixed in the units you set (px), so the pattern density stays visually consistent across screen sizes rather than stretching.
