I have a set of Styles that were first created inside the style attribute on a page.
I want to move it from being on the page itself into a stylesheet.
howe
I had this problem as well, and the reason was that the path had to be updated for some url() references since the css file was in another folder than the html file it previously was called from.
So basically
background-image: url('patterns/debut_dark.png');
had to be changed to
background-image: url('../patterns/debut_dark.png');
