SVG <pattern> Element Basics
Define a `<pattern>` in `<defs>` with a width and height that tiles. Set `patternUnits='userSpaceOnUse'` for absolute coordinates or `objectBoundingBox` for proportional tiling. Reference it as `fill='url(#patternId)'`.
- Define in <defs>: <pattern id='dots' width='20' height='20'>
- Draw one tile's worth of shapes inside the pattern
- Apply: <rect fill='url(#dots)' width='100%' height='100%'>
Using SVG Patterns as CSS Backgrounds
Inline SVG patterns in CSS using a data URI. Encode the SVG as a URL-safe string and set it as `background-image`. This avoids an extra HTTP request and works in all browsers.
- background-image: url('data:image/svg+xml,...')
- Encode special characters: # → %23, < → %3C
