CSSNamespaceRule: namespaceURI property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The read-only namespaceURI
property of the CSSNamespaceRule
returns a string containing the text of the URI of the given namespace.
Value
A string containing a URI.
Examples
The stylesheet includes a namespace as the only rule. Therefore the first CSSRule
returned will be a CSSNamespaceRule
. The value of the namespaceURI
property will be http://www.w3.org/1999/xhtml
.
css
@namespace url(http://www.w3.org/1999/xhtml);
js
let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0].namespaceURI); //http://www.w3.org/1999/xhtml
