Tileable Patterns with <pattern>
The SVG <pattern> element defines a tile the browser repeats to fill a shape. A few lines create a grid or dot background that stays razor-sharp at any zoom and weighs far less than a PNG tile.
- Define one tile in <pattern> and repeat it
- Crisp at any zoom, unlike raster tiles
- Tiny file size compared to PNG backgrounds
Using It as a CSS Background
Inline the pattern SVG or reference it via background-image with a data URI. Adjust spacing and stroke color with variables to match your design system.
- Inline the SVG or use a data-URI background
- Control spacing and color with CSS variables
- Layer over gradients for depth
Frequently Asked Questions
Why use SVG for a grid background instead of CSS gradients?
SVG patterns give precise control over line weight and spacing and stay crisp, while repeating-gradient grids can blur on subpixel rendering.
Can I use an SVG pattern as a CSS background-image?
Yes — encode the SVG as a data URI and set it as background-image, or inline the SVG and reference the pattern with fill='url(#id)'.
