Pure CSS Patterns

All patterns are created using CSS gradients (linear-gradient, radial-gradient, conic-gradient) and background-size. This technique offers several advantages over image-based patterns:

• Zero HTTP Requests — Faster loading, no additional files to download
• Infinitely Scalable — Patterns look crisp at any size or zoom level
• Easy to Modify — Change colors or sizes with a simple CSS edit
• Responsive — Works perfectly on all screen sizes
• Small File Size — A few lines of CSS vs. image files

Common Use Cases

• Card and container backgrounds
• Decorative dividers and borders
• Loading states and placeholders
• Presentation slides and graphics
• Social media graphics

Tips for Great Patterns

• Use subtle patterns (low opacity or similar colors) for backgrounds behind text
• Bold patterns work best for decorative elements without text overlay
• Combine with CSS background-blend-mode for advanced effects
• Test patterns at different sizes to ensure they tile seamlessly
• Consider accessibility — high contrast patterns may be distracting
