The following code is used to ensure proper functionality of webfonts across all browsers:
@font-face {
font-family: 'TradeGothic-BoldCondensedNo20';
src: url('../fonts/tradegothic/trade-gothic-lt-std-bold-condensed-no-20.eot?') format("embedded-opentype"),
url('../fonts/tradegothic/trade-gothic-lt-std-bold-condensed-no-20.woff') format('woff'),
url('../fonts/tradegothic/trade-gothic-lt-std-bold-condensed-no-20.ttf') format('truetype');
}
Despite this effort, there are issues with compatibility in IE8 and earlier versions.
