A simple trick to allow for custom font faces on the web. the @font-face property allows designers to host fonts on their site and then browsers download the font and display the text using the custom font.
Below are links to True Type font TTF to Embeded Open Type EOT converters. The EOT font is required for Internet Explorer while Firefox, Opera and Safari all support TTF.
View this pages source code and examine the Styles to see how these custom font faces can be achieved. There was a little work around to get it to function in Opera, a great little article with code examples can be found at Readableweb.
Please note that very few fonts are licenced for the web. Be careful of copyright infringement.
