Look for the the font-family names below. These names are case sensitive. Add the following line at the beginning of your stylesheet:
@import url(fonts/obelixpro.css);

NOTE: Add a slash in front of fonts/ if you are not using local fonts. After importing this style sheet into your CSS, you may use that font-family name in one or more of your own CSS rules.
