<svg> - SVG: Scalable Vector Graphics 编辑

The svg element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.

Note: The xmlns attribute is only required on the outermost svg element of SVG documents. It is unnecessary for inner svg elements or inside HTML documents.

html,body,svg { height:100% }

<svg viewBox="0 0 300 100" xmlns="http://www.w3.org/2000/svg" stroke="red" fill="grey">
  <circle cx="50" cy="50" r="40" />
  <circle cx="150" cy="50" r="4" />

  <svg viewBox="0 0 10 10" x="200" width="100">
    <circle cx="5" cy="5" r="4" />
  </svg>
</svg>
