Hi Louis,
What you're describing is called, in generic terms, "interaction."
Interaction is where the user does something, and the user interface (the
browser) does something in response. Once you start talking about
interaction, you're in the realm of programming.
There are 2 distinct types of programming associated with web pages:
Client-side (in the browser) and Server-side (HTML content is
dynamically-generated on the server in response to different things).
Client-side programming is done with JavaScript, and you might Google
JavaScript to start learning it. Server-side programming is done using ASP
(on a Windows Server), PHP, or some other server-side programming
technology. There are web sites (like mine:
http://www.takempis.com) that
can help you learn server-side programming as well.
Other than this general guidance, I can't provide you with any more
information, as your question was of a general nature. If you have a
specific requirement for your web, please describe it fully, and perhaps we
can help you come up with a specific solution.
