About CSS Background Pattern Generator

Because there's no image to request, patterns cost zero extra HTTP requests, stay crisp at any resolution, and can be recolored by changing a single value. The live preview is rendered from the real CSS, and everything is generated in your browser.

Frequently asked questions

How do CSS-only patterns work?
They use repeating-linear-gradient and radial-gradient as the background-image, with background-size and background-position tiling the result. No image file is ever requested.
Will these patterns stay sharp on retina screens?
Yes. Gradients are painted by the browser at the device's own resolution, so they stay crisp where a bitmap tile would blur.
Can I change the pattern colors later?
Yes — swap the two color values in the copied CSS, or wire them to CSS custom properties to theme the pattern at runtime.
Do CSS patterns hurt performance?
They remove an HTTP request entirely, which is usually a net win. Very small tiles stretched over very large areas do more paint work, so keep the tile size sensible for full-page backgrounds.
