CSS was ignored due to mime type mismatch

“CSS was ignored due to mimetype mismatch”.
This was the issue I was facing for one of my ASP.Net application, although, things were pretty straight forward.


A typical ASP.NET WebForm having masterpage that linked to MyStyles.css as follows:
<link href=”MyStyles.css” rel=”stylesheet” type=”text/css” />

I was using Internet Explorer version 9 and later tested on version 10 as well but find the same problem.
I did a lots of googling for the solution and finally find out that we need to enable a feature in IIS and i.e. Site Content feature.

Following microsoft blog link describe how to add that feature on Windows Server 2008.

    As a web developer, I experienced this many times and I know for a fact that this has to do with a complication to the application such a mismatch with the file and the content. The truth is that the Internet Exporer is just not a user friendly browser for any web development.
