id
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The id
attribute assigns a unique name to an element.
You can use this attribute with any SVG element.
Example
<svg
width="120"
height="120"
viewBox="0 0 120 120"
xmlns="http://www.w3.org/2000/svg">
<style>
<![CDATA[
#smallRect {
stroke: #000066;
fill: #00cc00;
}
]]>
</style>
<rect id="smallRect" x="10" y="10" width="100" height="100" />
</svg>
Usage notes

- <id>
-
Specifies the element's ID. The ID must be unique within the node tree, must not be an empty string, and must not contain any whitespace characters.
Note: You should avoid the use of
id
values that would be parsed as an SVG view specification (e.g.,MyDrawing.svg#svgView(viewBox(0,200,1000,1000))
) or a basic media fragment when used as a URL target fragment.It must be valid in XML documents. A stand-alone SVG document uses XML 1.0 syntax, which specifies that valid IDs only include designated characters (letters, digits, and a few punctuation marks), and do not start with a digit, a full stop (.) character, or a hyphen-minus (-) character.
