"The stylesheet was not loaded because its MIME type, "text/html" is not "text/css" [closed]

Question

I have a javascript application and when I run it on firefox I am getting the following erro on the console:

"The stylesheet was not loaded because its MIME type, "text/html" is not "text/css".

DumbStuck!!

EDIT: Note that it tells that "The stylesheet ABCD..." But ABCD is actually an HTML file.

Edit (ANSWER) : Actually I had wrongly put href="", and hence the html file was refenecing itself as the CSS. Mozilla had the similar bug once, and it is from there I got the answer. But everyone's else answers helped me too. Thanks.

Answer 1

In the head section of your html document:

<link rel="stylesheet" type="text/css" href="/path/to/ABCD.css"> 

Your css file should be css only and not contain any markup.

Answer 2

Actually I had wrongly put href="", and hence the html file was referencing itself as the CSS. Mozilla had the similar bug once, and I got the answer from there.
