Thank you for your feedback.
I'm interested and know how to implement everything on the front-end - structure and content (HTML), presentation and positioning (CSS), and interactivity (JavaScript).
The content would have to be provided by the client, but I can perfectly deal with the rest (if the client hasn't a designer, for instance).
If the client provides designs and interaction guidelines, no problem at all, I know (or will learn) how to implement them - using semantically appropriate HTML code, custom CSS and JavaScript (JS).
I really love a handcrafted package of HTML, CSS, and JS. That's what I would like to do, if there's demand - thence my question :).
