I have two columns, one with navigation, and the other with content. These are both divs. How do I refresh the content column upon clicking on a link in the links column? Should work in various screen sizes in a fluid layout (columns will stretch and squeeze).

I know I can make each link a separate HTML page and just repeat the navigation over and over on each page, but the number of links will get too long for that, making it a chore to update the links on every page with each change.

Maybe this belongs in the CSS column; I'm not sure.
