Ask HN: Tips on Learning Front End Web Development?

Hey guys. I decided I wanted to start learning some front end development and wanted to see if I can get some advice. I am trying to plan out a curriculum for myself, but I don't think I understand the overlap between some languages and how they come into play. I already know some python and some java. I figured it would make the most sense to start with html/css. After that I am not sure what makes the most sense. Do I learn django(figured since I know python its easier to go to django than rails)? javascript/coffescript? Do I need to learn a database language? If so, which is best? MySQL? MongoDB?

Thanks for the help.
