Whats the most popular language for coding web pages at the moment?

If you have prior programming experience, you should pick up html very quickly, it is a very simple markup language. This goes hand in hand with css, which is used to style html, again, very easy, just run through the tutorials at w3schools.com. For functionality, you may want to learn php, or ruby on rails is becoming very popular. These are server-side languages, so you will need a localhost to develop on your computer, do a search for WAMP and download one of the packages. These come bundled with apache(the server) php(the scripting language) and mysql(database) that will run on your local computer.
