The href property of the StyleSheet interface returns the location of the style sheet.
This property is read-only.
A string containing the stylesheet's URI.
Assume the <head> contains the following:
<link rel="styleSheet" href="example.css" />Then, if you open the HTML page via a file:// URL on Windows, and run the following script:
console.log(document.styleSheets[0].href);The result looks like: "file:////C:/Windows/Desktop/example.css".
If the style sheet is a linked style sheet, the value of its attribute is its location. For inline style sheets, the value of this attribute is null.
