HTML question time!

Okay so I have this site I’m working on see? And the game itself is in greatest journal right? Well one of the features I want on the website is a small marquee in a cell on one of the tables, with the current posts to the site shown and each title linked to the entry in question. In execution it'd be much like when one is at a bus terminal or airport and a marquee has the information of what is incoming or outgoing, but you know with links to the object itself and whatnot.

Long story short, is this possible in HTML, and moreover is there any place that says how to do it?
