Create a repeating background without an image
Choose dots, diagonal stripes or a checkerboard and set a tile size plus two colors. The generator builds a CSS gradient background and shows it in a live browser preview. A background shorthand includes the generated image, tile size and base color, so the copied rule can be applied to a section or decorative element without downloading an additional raster asset.
Keep patterns subordinate to content
Dense patterns can make text difficult to read even when each chosen color looks attractive alone. Use a separate solid surface behind long text, test the actual foreground contrast and inspect the design at different browser sizes. The dot radius is fixed while tile spacing changes. These patterns are decorative and convey no information on their own; provide semantic content independently of the generated background.
