I'm currently working with on a site that has a lot of pages. Included on every html page, are 3 navigation areas (basically, 3 html tables with hyperlinked text navigation). Since this navigation is replicated throughout the entire site, I would like to stip the nav out, and have it in a separate file that is "called" by every html page, so if I need to make a change, I only have to change the "nav" page, and the results are replicated throuhout the site, instead of manually changing the nav on every page. My question is, what's the best (aka easiest) way to do this? My site is hosted on a unix server... I believe that this cannot be done in CSS, because that is only for site appearance/formatting settings....correct?
