CSS Background Pattern Generator

Build pure-CSS background patterns from twelve styles and copy the code. Patterns that CSS gradients express exactly are output as gradients; the rest come with an SVG data URI fallback that tiles perfectly.

Which output do I get?

  • css — stripes, checks, dots, circles, diagonals and crosshatch come out as layered linear-gradient/radial-gradient values. They are crisp at any size and cost nothing to download.
  • svg — zigzag, triangles, hexagons, waves, bricks and diamonds are emitted as a compact inline SVG data URI, because gradients cannot describe those shapes exactly.
  • The background colour is always set separately, so a pattern can sit on any tint.

About this tool

This CSS background pattern generator builds repeating backgrounds without a single image file. Twelve styles are available — stripes at any angle, gingham checks, polka dots, concentric rings, zigzags, diagonal hairlines, crosshatch, triangles, hexagons, scalloped waves, running-bond brick and harlequin diamonds — each with control over the two colours, the pattern opacity, the tile size, the line thickness and the angle.

Where CSS gradients can describe the pattern exactly they are used, which keeps the output tiny and infinitely crisp. The remaining shapes are emitted as a compact SVG tile in a data URI that repeats seamlessly, and the preview can be switched between the two so you can see they match. Patterns are shown at three element sizes so you can judge how the tile reads on a card or a button as well as a full-width section. Everything is generated in your browser and nothing is uploaded.
