id

The id attribute assigns a unique name to an element.

You can use this attribute with any SVG element.

Example

html

<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

Value <id>
Default value None
Animatable No
<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.
