Why use CSS Background Patterns?
CSS patterns are a lightweight, high-performance alternative to traditional backgroundImage files (PNG/JPG). Since they are mathematically generated by the browser, they are infinitely scalable and take only a few bytes of code.
Polka Dots
Uses radial-gradient. Great for a soft, playful look. Often used in hero sections and cards.
Stripes & Diagonal
Uses linear-gradient. Vertical or diagonal stripes create a sense of movement and structure.
Checker & Grid
Perfect for technical or retro designs. Grids are excellent for dashboard backgrounds or data visualization areas.
ZigZag & Waves
Complex patterns created by layering multiple gradients. These provide a textured, premium feel to website sections.
Optimization Tips
- Performance: Patterns are rendered by the GPU. Use them instead of large high-res images to improve LCP (Largest Contentful Paint) scores.
- Subtlety: The best patterns are often very subtle. Use a pattern color that is only slightly different from your background color (adjust Opacity for this).
- Dark Mode: You can easily swap pattern colors using CSS Variables to support dark and light themes without loading new assets.
