This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The ownerNode property of the StyleSheet interface returns the node that associates this style sheet with the document.
This is usually an HTML <link> or <style> element, but can also return a processing instruction node in the case of <?xml-stylesheet ?>.
A Node object.
Assuming the <head> contains the following:
<link rel="stylesheet" href="example.css" />
Then:
console.log(document.styleSheets[0].ownerNode); // Displays '<link rel="stylesheet" href="example.css">'
For style sheets that are included by other style sheets, such as with @import, the value of this property is null.
