This is the MAIN window of our frameset, and holds "main.html". Over on the left is the TOC window, with "tableofcontents.html". The text in the Table of Contents is all contained within a table set to 100% width and height, so you can see how the MARGINWIDTH and MARGINHEIGHT we specified in the frameset have affected it. Notice also the border between the two windows.

There's a borderline, but no scrollbar because the contents page is small enough to fit into the window. This frame has a scroll bar... so scroll down...
