The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

SVG shapes, gradients, filters, and patterns are composed inside a viewBox and serialized as a standalone vector background. The viewBox and preserveAspectRatio settings determine how that coordinate system fills a target box. The output remains a vector scene instead of a fixed pixel bitmap.

  • Vector backgrounds remain resolution-independent and recolorable.

Worked example

Floating circles over purple gradient
Generate a gradient background with floating circles
Input
											Style: circles
Width: 800
Height: 600
Color1: #667eea
Color2: #764ba2
Seed: 42
Opacity: 0.5
Output

When to use this

Hero sections, social cards, and responsive design panels generate SVG backgrounds.

Edge cases

  • preserveAspectRatio meet can leave letterboxing.
  • Filters can enlarge painted bounds beyond the viewBox.
  • gradientUnits changes whether stops follow the object or the page.
