General description

@font-face {
font-family: 1″FontName”;
src: 2url(‘fontfile.eot’);
src: 3url(‘fontfile.eot?iefix’) format(‘eot’),
4url(‘fontfile.svg#FontName’) format(‘svg’),
5url(‘fontfile.ttf’) format(‘truetype’),
6url(‘fontfile.woff’) format(‘woff’);

  1. The name of the font for the further usage in the stylesheet at the font-family property. If the font should be assigned to all <h2> headlines for example you have to write <h2> { font-family: “FontName”, sans-serif }. Can be choosen freely.
  2. Optional. The eot fontfile. Can be omitted if you don`t want to support Internet Explorer prior to version 9 (including semicolon).
  3. Optional. Can also be omitted for Internet Explorer < 9. ?iefix prevents IE6 from interpreting all of the following. If the whole IE family (6 to 9) should be supported, 2 and 3 are needed.
  4. Optional. Can be omitted if iPad versions prior to iOS 4.2 shouldnt be supported. FontName is the same as at 1.
  5. The ttf fontfile. Necessary to support (Mobile) Safari and Opera.
  6. The woff fontfile for all modern browsers (best choice).
