css background generator

How to use the css background generator

  1. Pick a pattern: dots, grid, stripes, waves, checkerboard, hexagons.
  2. Adjust tile size, spacing, and colors.
  3. Toggle a fade mask for vignette-style falloff.
  4. Copy CSS — pure CSS, no images.

When to use it

Use CSS patterns for subtle page-level texture (repeating dots, grids) that add polish without the HTTP cost or Retina blur of image-based patterns. Avoid busy patterns on text-heavy pages — they fatigue readers. Alternative: heropatterns.com ships SVG; our tool ships CSS-only for smaller payloads.

Frequently asked questions

Are these patterns responsive?
Yes — tile size is set in rem or %, so the pattern scales with the viewport. Set fixed px if you want stable tile size across devices.
Can I animate the pattern?
Yes — animate background-position to make the pattern scroll, creating subtle motion.
Do these patterns cost more than a plain color?
Marginally — the browser composites a repeating gradient instead of a solid fill. On modern GPUs the cost is unmeasurable; on low-end mobile it can cost a few ms of paint time on large areas.
