Frequently Asked Questions

CSS background tiles an image (or gradient) across the element using background-repeat: repeat. Combined with background-size, you control the tile dimensions. Linear-gradient and radial-gradient can create tile-able patterns without any external images. The key is designing a tile that seamlessly repeats both horizontally and vertically.

SVG patterns (using <pattern> element inside <defs>) support complex geometric shapes that are hard to achieve with CSS gradients alone. You can embed an SVG as a data URI in background-image: url("data:image/svg+xml,..."). This approach works for patterns like hexagons, complex tessellations, and custom shapes while remaining purely declarative.

CSS gradient-based patterns are rendered by the GPU and are generally very performant. They require no network request (unlike PNG/SVG files), adapt to any resolution, and scale perfectly. For very complex patterns with many gradient stops or overlapping backgrounds, performance can degrade slightly, but for typical use cases they are faster than image-based alternatives.
