@ Shockwave:
The jobs range from being a member of a web programming team, specialising in one or more web languages (the more you know, the better), to team manager, and even project managers.
As Benny! has said, there are many areas of web design, so it is probably best to start with HTML, and then decide to specialise in either server technologies (CGI, PHP, ASP, PERL, databases, etc) which can be used to write HTML, or client technologies, such as CSS, JavaScript, ActionScript, Flash.
Then there's the openings for Graphic Designers, Animators, and even Sound FX people on the team as well, depending on where you live and on which companies are based near where you live, but with web based companies, you could even work from home.
This is probably the best place to start looking for information on the CIW course through Skills Train:
