💡 About CSS patterns

  • These backgrounds are pure CSS gradients — no image files, and they stay sharp at any scale.
  • Adjust the two colors and the tile size to fit your design.
  • Apply the background (and background-size) to any element.

What is a CSS pattern?

A CSS pattern is a repeating background built entirely from gradients rather than an image file. Using linear, radial, and conic gradients with background-size, you can create stripes, polka dots, checkerboards, grids, and geometric textures directly in code. Because there is no image to download, patterns load instantly, stay perfectly crisp at any zoom, and can be recolored by changing a single value.

How to use the pattern generator

It is instant:

  • Pick a pattern style — stripes, dots, checkerboard, grid, and more.
  • Choose the foreground and background colors.
  • Adjust the tile size to make the pattern denser or larger.
  • Copy the background CSS and apply it to any element.

How CSS gradient patterns work

The trick is repetition. A repeating-linear-gradient creates stripes by alternating colors at fixed intervals, and setting an angle makes them diagonal. Dots and grids use a small gradient tile combined with background-size so it repeats across the element. Checkerboards use a repeating-conic-gradient. Each pattern is just a compact background declaration, sometimes paired with a background-color and background-size, which this tool assembles for you.

Where to use background patterns

Subtle patterns add texture without the weight of an image: a faint grid behind a hero section, soft diagonal stripes on a card, or light dots as a section divider. They work well as low-contrast backgrounds that sit behind content, or as bold decorative panels. Because they are vector gradients, the same pattern looks sharp on a phone and a 4K monitor alike, and you can scale it by adjusting one size value.

Keeping patterns readable

A background pattern should never fight the content on top of it. Keep the two colors close in value for anything sitting behind text, so the contrast between your text and the background stays high. Reserve bold, high-contrast patterns for purely decorative areas with no overlaid text. If a pattern feels busy, increase the tile size or lighten the foreground color to calm it down.

Pro tip

Store your pattern's colors as CSS variables so you can recolor every patterned surface at once, and reuse the same tile size across sections for a consistent rhythm. For solid-color gradients behind the pattern or as an alternative, our CSS Gradient Generator complements this tool.

FAQ

Is this CSS Pattern Generator free?
Yes. It is completely free, runs in your browser, and requires no account or sign-up.
Are CSS patterns better than background images?
For geometric patterns, usually yes. They need no image file, add no extra network request, stay sharp at any size, and can be recolored by changing a value.
How do I make the pattern bigger or smaller?
Adjust the tile size. It controls the repeat interval, so a larger size spreads the pattern out and a smaller size makes it denser.
How do I apply the pattern to an element?
Copy the generated background (and background-size, if present) and add it to the element's CSS. It tiles automatically across the element.
Can I use a pattern behind text?
Yes, but keep the two colors close in value so the pattern stays subtle and your text remains readable. Save bold patterns for decorative areas.
Do CSS gradient patterns work in all browsers?
Linear and radial gradient patterns work everywhere. Conic-gradient patterns (like checkerboards) are supported in all current browsers.
How do I recolor a pattern later?
Change the color values in the background declaration, or store them as CSS variables so you can update every patterned element from one place.
