I'm wondering if someone can point me in the right direction for creating an Ubuntu theme using pure HTML/CSS/JS. I'm hoping there is some existing back-end to GNOME3 or Unity I can simply install and create my theme as easily as I'd create a website.
P.S.: If there is no such way to create a theme or add to the default theme, then alternatively if you can, please give me some details about what systems/libraries I'd have to hook into or extend. I'm a C++ developer so I suppose if I really have to, I can make this possible. Hoping though that something already exists.
Thanks for your help!
