Using Frames and Framesets

16

Different browser versions on different operating systems treat the border settings for

individual frames differently. To complicate the situation, sometimes the settings on the

overall frameset control how the individual frame border settings act. For example, if the frameset bor-

der is set to Default, and the individual frame border is set to No, the border still appears in Internet

Explorer 6.0 running on Windows—but as flat, rather than three-dimensional. If you elect to set the

border property for an individual frame, be sure to test on as many browsers and platforms as possible.

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.
