Yeah you have to have all the fonts for all the different browsers. Each one takes a different one. They have to be in a specific order as well or it'll fail. I usually just make the kits with http://www.fontsquirrel.com/
@kleinbl00 - You think this is too light? @font-face {
font-family: 'essays1743bold';
src: url('font/essays1743-bold-webfont.eot');
src: url('font/essays1743-bold-webfont.eot?#iefix') format('embedded-opentype'),
url('font/essays1743-bold-webfont.woff') format('woff'),
url('font/essays1743-bold-webfont.ttf') format('truetype'),
url('font/essays1743-bold-webfont.svg#essays1743bold') format('svg');
font-weight: normal;
font-style: normal;
}
