how to create responsive website

Answer 1

At the basic CSS level, start using % for units instead of pixels.
Or you could use an existing responsive framework like bootstrap or foundation.

Answer 2

If you don't have a server-side language available to you (php, asp, cgi) then you can use hard coded javaScript on your page. Either way using basic javaScript or jQuery you can provide a page with interactive responses and reactions.

EDIT: What specifically do you mean by responsive? Reactive to browser window changes, or user element interactions?
