You are getting good advice from everyone. Learn HTML (and the HTML5 specifics) and learn how to use jQuery, javascript and css. Every front end dev needs to learn css and be totally comfortable with it.
My 2 cents on starting with javascript/jQuery: learn how to select items by id, using css selectors etc. Then learn how to get and set values of different input types, setting css properties, showing and hiding elements etc. All this is basic but will give you a good start. Also good to learn how to properly use ajax and jquery to and populate list boxes or something just for practice.
Learn how to use Firebug and the browser tools like Chrome dev tools to debug javascript and css issues. Get familiar with Fiddler or similiar tools if you aren't already.
Just some idea's on things you will always find yourself using or needing to know so you can figure out how some library is working which helps you debug.
