> A CSS Background Pattern Generator builds repeating decorative backgrounds — stripes, dots, grids, checks, zigzags, crosshatch — from pure CSS gradients with no image files, and gives you copy-ready CSS.

Pick a pattern, set two colors, and tune size, thickness, and angle to get a seamless repeating background made entirely from CSS gradients. 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.

## Features

- Six patterns: stripes, dots, grid, checks, zigzag, crosshatch
- Pure CSS gradients — no image files or extra requests
- Two-color control with pickers and hex inputs
- Size, thickness, and angle controls
- Live preview rendered from the generated CSS
- Copy-ready CSS, generated in your browser

## Use cases

- Adding subtle texture to a hero or section background
- Building a grid or dot backdrop for a canvas or editor UI
- Creating a striped loading or placeholder surface
- Replacing a repeating background image to cut requests

## How to use it

1. **Pick a pattern** — Choose stripes, dots, grid, checks, zigzag, or crosshatch.
2. **Set colors and scale** — Adjust the base and pattern colors, then size, thickness, and angle.
3. **Copy the CSS** — Copy the generated rule into your stylesheet.

## When to use it, and when to use something else

- **vs A repeating PNG background** — use CSS Background Pattern Generator when you want zero extra requests, crisp rendering at any DPI, and instant recoloring. Use A repeating PNG background when the texture is photographic or too organic for gradients.
- **vs An SVG pattern** — use CSS Background Pattern Generator when you want a one-line CSS declaration with no extra markup. Use An SVG pattern when you need complex multi-shape artwork.

## 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.
