"C:\svg\style.css" is a relative URL, you need to make it absolute.
When the browser renders the file it provides the base url of the document
(which is likely a 'file:' URL) which is used to turn the relative URL
into
an absolute URL. I suspect all you need to do is use:
"file:///C:/svg/style.css"
Typically I will use the JDK provided functionality
new File("C:\svg\style.css").toURL()
Which almost always gives the 'expected' behavior for files...
