About CSS Background Patterns

How It Works

CSS background patterns use background-image with CSS gradients (linear-gradient, radial-gradient) combined with background-size and background-position to create seamlessly repeating patterns without any image files.

Performance

CSS-only patterns are resolution-independent and require zero HTTP requests, making them ideal for decorative backgrounds. They render efficiently on all screen densities including retina displays.

Browser Support

CSS gradient patterns are supported in all modern browsers. The repeating-linear-gradient and radial-gradient functions have excellent cross-browser compatibility.

Tips

For best results, use subtle color differences between primary and secondary colors. Combine patterns with opacity or overlay them on solid backgrounds for sophisticated visual effects.
