relative file path to fonts in css file

URLs in CSS files are relative to the CSS file.

url('fonts/icomoon.eot?hsw0h3'); means http://example.com/css/fonts/icomoon.eot?hsw0h3, but your screenshot of your directory structure shows you need http://example.com/fonts/icomoon.eot?hsw0h3.

Add ../ or /
