I have a really good understanding of the legacy way of creating themes and loading them on my phone. I dont have any experience with HTML. My question is, How do you create a full theme with HTML, CSS and JS? I've seen some simple mods like weather and calendar widgets, but nothing for anything else. Is there a set of template libraries out there were i could use that as a base for creating my theme? Or am I just gonna have to learn how to write code to get what i want.

Its not that big of a deal, just a question that came up when venturing for new options of creating a theme for my iphone. Thought it would be kinda cool to have a phone that runs on minimal png's and driven with HTML, CSS and JS.
