CSS Background Pattern Generator
Generate pure CSS repeating patterns — no images needed. Pick a pattern, set colors and size, then copy the code.
What Are CSS Background Patterns?
CSS background patterns are repeating visual textures created entirely with CSS gradient functions — no image files required. They use repeating-linear-gradient, repeating-radial-gradient, and stacked linear-gradient layers to produce stripes, grids, dots, checkerboards, zigzags, and other geometric patterns at any scale.
Because they are vector-based and resolution-independent, CSS patterns look crisp on any screen — from low-DPI monitors to high-resolution Retina displays. They render instantly without network requests and can be changed at any time by adjusting a few property values. This makes them far more flexible than raster image patterns for UI backgrounds, cards, hero sections, and decorative elements.
All patterns generated by this tool are pure CSS. Paste the output directly into your stylesheet, Tailwind config, or CSS-in-JS file. No dependencies, no images, no JavaScript required at runtime.
How to Use This Generator
Select a Pattern Type: Stripes, Grid, Dots, Checkerboard, or Zigzag. Each uses a different gradient technique optimized for that shape.
Choose a Foreground color (the pattern color) and a Background color. Use the Size slider to scale the tile — smaller values produce denser patterns, larger values create a bolder look. For Stripes, the Angle slider rotates the direction from 0° (vertical) to 90° (horizontal) to 45° (diagonal).

Worked Examples
Subtle Grid Background
Grid pattern, Size 24px, light gray foreground on white. A minimal grid is a classic choice for dashboards, diagram canvases, and developer tools where structure is implied without being distracting.
Bold Diagonal Stripes
Stripes pattern, Angle 45°, Size 20px, brand color on white. Diagonal stripes add energy to hero banners, loading states, and alert bars. Wider sizes (40–60px) create a retro feel.
Dot Matrix Card
Dots pattern, Size 16px, muted foreground. Small dot grids work well as card backgrounds, notebook-style layouts, and code editor backgrounds where a texture is needed without overpowering the content.
Frequently Asked Questions
What CSS properties create background patterns?
CSS background patterns use repeating-linear-gradient and repeating-radial-gradient. By stacking multiple gradient layers with transparent gaps you can produce stripes, grids, dots, checkerboards, and zigzags without images.
Are CSS background patterns better than image patterns?
Yes for most use cases. CSS patterns are resolution-independent (sharp on any screen), require zero network requests, and can be changed instantly in code. Raster images can look blurry on high-DPI screens and require file management.
How do I make a CSS checkerboard pattern?
A CSS checkerboard uses four stacked linear-gradient layers at 45° and −45° angles. Set background-size to your tile size and offset each layer by half the tile using background-position. This generator handles the math automatically.
How do I change the size of a CSS background pattern?
Change the background-size property. For gradient-based patterns, also update the pixel stop values inside the gradient functions to match. This generator keeps both in sync automatically when you adjust the Size slider.
Can I use CSS background patterns with border-radius?
Yes. CSS background patterns respect border-radius and clip to the element's border-box. Apply them to rounded cards, circles, pills, or any shaped element.
Do CSS gradient patterns work in all browsers?
repeating-linear-gradient and repeating-radial-gradient are supported in all modern browsers including Chrome, Firefox, Safari, and Edge. No vendor prefixes are needed for modern browser targets.
