# CSS Background Pattern Generator — Stripes, Dots, Grids & Noise

> Generate repeating background patterns in pure CSS — no image files to host.

CSS background patterns are built from repeating gradients rather than image files — a stripe is one repeating-linear-gradient, a checkerboard is two offset by half a tile, and dots are a radial gradient tiled by background-size. They scale to any resolution, cost nothing to download and can be recoloured with a single value.

## FAQ

### Why use CSS rather than a background image?

No extra request, no file to host, perfectly sharp at every pixel density, and the colours are one value away from being themeable. A tiled PNG has none of those properties and is usually larger than the CSS that replaces it.

### Why does my stripe pattern shimmer when scrolling?

Thin high-contrast lines alias against the pixel grid, especially at fractional device pixel ratios. Increasing the line thickness by a pixel or reducing the contrast fixes it — this is the same moiré effect that makes fine checks flicker on video.
