CSS Pattern Generator

Dots, stripes, grid, checkerboard, diamond weave, graph paper and starfield backgrounds built from pure CSS gradients -- with angle, thickness, opacity and colour controls, presets, randomize, and export to CSS, Tailwind, SCSS or React.

What this tool does

Builds a repeating background pattern entirely from CSS gradients — no PNG or SVG file to host, load, or keep in sync with a colour scheme. Every pattern is one background-image declaration.

Seven pattern types

Dots, stripes, a line grid, a checkerboard, a diamond weave, graph paper (with both major and minor gridlines), and a starfield made of two overlapping dot layers at different sizes and opacities for depth. Each is a real gradient trick — a repeating-linear-gradient for stripes, layered radial-gradients for dots and starfield, and so on — rather than a raster image behind the scenes.

Tuning the look

Pattern colour, background colour, opacity, spacing, line thickness, and (for stripes) angle each have their own control, plus an X/Y offset to shift the whole pattern within its tile. Because it's pure CSS, the pattern colour can be swapped for a brand colour without regenerating an image asset.

Presets and randomizing

Seven presets cover common looks — Subtle Dots, Blueprint Grid, Graph Paper, Candy Stripes, Chessboard, Diamond Weave, and Starfield Night — plus a randomize button that picks a pattern type, colours, and spacing together for quick exploration.

Getting the CSS out

Export as plain CSS, a Tailwind arbitrary-value class string, SCSS, or a React inline style object, copyable with one click.

Frequently asked questions

Is my data uploaded anywhere?
No. The pattern is built and rendered entirely in the browser -- nothing is sent to a server.
Does this use an actual image file for the pattern?
No -- every pattern is built from CSS gradients only (repeating-linear-gradient and radial-gradient), so there's no image file to host, load, or update when a colour changes.
What pattern types are available?
Dots, stripes, a line grid, a checkerboard, a diamond weave, graph paper with major and minor gridlines, and a starfield made of two overlapping dot layers at different sizes.
Can I change the pattern colour without regenerating anything?
Yes -- since it's pure CSS gradients, changing the pattern or background colour updates the live preview and generated code instantly, with no image asset to redo.
What does the offset control do?
It shifts the pattern's starting position within its repeating tile on the X and/or Y axis, useful for aligning a pattern against another element on the page.
What export formats are available?
Plain CSS, a Tailwind arbitrary-value class string, SCSS, or a React inline style object -- selectable from a dropdown next to the code output.
