Font-Face Issues

[iAaron]

Dear MyBB Community,

I am trying to add a specific font to a specific div, and the @font-face CSS element is not taking it's affect, as it does on the main website itself. Does MyBB have issues with the @font-face tag? How do I properly display specific fonts via MyBB?

CSS (global.css)

/* CUSTOM FONT(S) */

@font-face {
	font-family: "Dark";
	font-weight: normal;
	font-style: normal;
	src: url('images/arcadia/custom/font/dark.eot');
	src: local('Dark'), url('images/arcadia/custom/font/dark.ttf') format('truetype');
}

#header-nav li {
        font-family: "Dark";
	margin: 0 auto;
        display: inline;
}

Thank you so much,
Aaron Brewer
