Frame Content:
Basically treat each frame as a separate web page. You can edit the pages individually or use the frameset page and see all frames at once in your frameset.
The most complicated part of frames and Dreamweaver is making sure to save all your frames and keep track of what is called what and where it goes.
If you see missing information in the "src" box when you select the frame in the frame panel, you know that you need to save and name your frame.
