title: how to know format of fonts
body: <p>I am going to use @font-face. So I copied <strong>corbel</strong> font to my directory and there it shows 4 fonts <code>CORBEL_0.TTF , CORBELB_0.TTF , CORBELI_0.TTF , CORBELZ_0.TTF</code> and next I copied <strong>Kozuka Gothic Pro</strong> font to my directory and there it shows 6 fonts <code>KozGoPro-Bold.otf , KozGoPro-ExtraLight.otf , KozGoPro-Heavy.otf , KozGoPro-Light.otf , KozGoPro-Medium.otf , KozGoPro-Regular.otf</code></p>
  
  <p>How to write src using @font-face rule?
  As in example url("../../css/fonts/League_Gothic.eot") format('eot'); the format eot , is it the extension of font? Anyone give me the idea for full syntax within @font-face.</p>
