Reference a CSS file in the File Library

This probably isn't helpful, but I can confirm it doesn't work! I've tried it a number of ways. The odd thing is that the browser recognizes it, reads the file, even identifies it as a stylesheet via the mime type, but for some reason doesn't apply the style

The link itself to File.php with the file unique identifier is actually fine. The problem is that when File.php serves the css file, it doesn't set the response header that allows the file to be interpreted as a style sheet. It should be 'text/css' but it's set to 'text/plain'. https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types#textplain Unless Qultrics adds CSS support to the files library, the only way I know to make this work is to load the file with javascript and inject the contents into a style block. This is likely more trouble than it's worth.

Just updating the thread that this is still an issue. All CSS files are being hosted externally, outside of Qualtrics for my projects.

Just for others who'd also try to solve this: I've tried to import the stylesheet using `<link rel="stylesheet" href="URL"> `and it also didn't help. Using the old Look&feel editor also not... @Pete_L : Have you tried to contact the Qualtrics support about this issue? I think this should work...

@fleb - You can go to the Look & Feel > Header > Source View and paste that html code there and it will work correctly 😀 That's how I'm currently handling it for my projects. I have not contacted Qualtrics support but will go ahead and put in a feature request for this now that the new "Idea" thread exists!
