{{SVGRef}}{{Deprecated_Header}}

The **`version`** attribute is used to indicate what specification a SVG document conforms to. It is only allowed on the root {{SVGElement("svg")}} element. It is purely advisory and has no influence on rendering or processing.

While it is specified to accept any number, the only two valid choices are currently `1.0` and `1.1`.

You can use this attribute with the following SVG elements:

- {{SVGElement("svg")}}

```html
<svg version="1.1" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
  <rect x="10" y="10" width="80" height="80" />
</svg>
```
