In-Depth Information
In addition, the frameset is defined as having no borders, but the first frame is supposed
to have a border. How do you resolve this problem? You can apply three simple rules:
Attributes in the outermost frameset have the lowest priority.
n
Attributes are overridden by attributes in a nested
<frameset>
tag.
n
Any
bordercolor
attribute in the current frame overrides previous ones in
<frameset>
tags.

Additional Attributes
Table 17.1 shows a few extra attributes for the
<frame>
tag. These attributes can give you
additional control over how the user interacts with your frames. Other attributes control
margins or spacing between frames and whether scrollbars appear when required.

screen by grabbing the borders and moving
them with the mouse. To lock the borders of
a frame and prevent them from being moved,
use the
noresize
attribute.

(Default) If the content of a frame takes up
more space than the area available, frames-
compatible browsers automatically add scroll-
bars to either the right side or the bottom of
the frame so that the users can scroll
