Learning HTML,XML, JAVASCRIPT, WEB AND CGI

:confused: Can any one out there tell me where an old fart like me can learn these languages on the web (cheaply or perhaps even for free) I 've been learning html from just viewing source on web sites but the rest are little too complex for this style of learning. I am a firm believer that a person can learn anything they set their minds to with out going to the traditional "school" of thought. If there are any good books I can learn this from please recommend them also. Thanks folks.:wave:

Start with HTML:

www.w3schools.com/html/

after that, you can work your way up to the other stuff. :)
