Additional limitations come into play when you try to implement one of your border modifications.
Because frames share common borders, it is difficult to isolate an individual frame and have the change
affect only the selected frame. As an example, Figure 16-11 shows a frameset in which the borders are set to
No for all frames except the one on the lower right. Notice how the left border of the lower-right frame
extends to the top, including the left border of the upper-right frame. You have two possible workarounds
for this problem. First, you can design your frames so that their borders do not touch, as in a multirow
frameset. Second, you can create a background image for a frame that includes a border design.

If you want to use isolated frame borders, you have to carefully plan your Web page frameset to avoid overlapping
borders.
Adding scroll bars
One of the features that has given frames the wide use they enjoy is the capability to enable or disable scroll
bars for each frame. Scroll bars are used when the browser window is too small to display all the information
in the Web page frame. The browser window??™s size is completely controlled by the user, so the Web
designer must apply the various scroll bar options on a frame-by-frame basis, depending on the look
desired and the frame??™s content.
