The front end technologies used by AP Web Design include HTML, DHTML (Dynamic HTML), CSS (Cascading Style Sheets), JavaScript (a client side scripting language), and of course graphic design. Feel free to browse through the links in the left-hand navigation menu for examples and more information regarding these technologies.
I have over 4 years experience in the front end graphical design & layout, hand-coding of html, dynamic html, and javascript for web pages, as well as the use of cascading style sheets.
For front end development, the importance lies in cross-browser compatability. This entails writing code that works for the various versions of Document Object Models (DOMs) of Microsoft's Internet Explorer, Netscape's Communicator, Konquerer for KDE desktop on linux, and Opera - to name a few.
