editing webpage templates

For a project at work, I have to update my departments intranet site and wanted to update the look by using a template. I downloaded the webpage template from freewebtemplates.com, but it wasn't quite what I wanted. The page had tabs on the top, a navigation bar on the left side, and the funkiest colors I've ever seen on a web page. I've used FrontPage a little to move information around and add text, but not to make the kind of changes that this template needed. Because of the information we've learned in this class, I've been able to go into the code, change the information in the css style sheet for the colors, and change the code on the main page for the tabs and the navigation bar. This stuff has already come in handy!
