CSS Background Pattern Generator

A background pattern generator produces repeating CSS backgrounds — dots, grids, stripes, zigzags, checkerboards — using gradients and background-size, with zero image assets. The result is a scalable, instantly-recolourable pattern that weighs less than 1 KB of CSS regardless of how big the patterned area is. Designers use them to add texture to hero sections, card backgrounds, empty-state illustrations, and 404 pages; developers use them as lightweight alternatives to SVG or PNG assets for interface decoration.

Every pattern here is built from the linear-gradient, radial-gradient, or conic-gradient CSS functions. A pattern is defined by two ingredients: the gradient (which paints one tile of the pattern) and background-size (which sets how big one tile is, so the browser tiles it across the element). Changing the size scales the pattern without distortion. Changing the colour is a single-variable edit. No other technique offers that combination.

Our gallery covers the eight most requested patterns. Dots are the most popular — small circles in a grid, perfect for subtle texture behind cards. Grid lines are ideal for technical/engineering aesthetics (think Figma, Framer, and dashboard backgrounds). Diagonal and horizontal stripes add motion and energy without being busy. Checkerboard is classic for transparency backdrops and retro themes. Zigzag and cross patterns are playful accents for illustrations and playful brands. The hex grid approximation uses two offset dot grids to produce a hexagonal rhythm cheaply.

Performance is outstanding. CSS gradient patterns are rendered directly by the compositor with no network request. They scale infinitely without jaggies or pixelation. They respect prefers-reduced-transparency implicitly (no JS animation needed). And they work in every evergreen browser — conic gradients were the last to land and have been supported everywhere since 2022.

Accessibility notes. Patterns are decorative; ensure text that sits on them has sufficient contrast. For text-heavy cards, keep the pattern subtle — low contrast between foreground and background so the pattern reads as texture rather than a visual element. For users who prefer reduced motion, static patterns are fine; avoid animating the background position on patterned areas if you care about accessibility.

1. Pick a pattern from the eight presets in the sidebar.
2. Tune colours — foreground for the motif, background for the canvas.
3. Adjust scale — smaller for subtle texture, larger for graphic accents.
4. Copy the CSS and paste into your stylesheet.
