HTML Frames
Agenda
Advantages and disadvantages of frames
FRAME template
Defining rows and cols in a FRAMESET
Common FRAME and FRAMESET attributes
Nested frames
Targeting a document to a named
FRAME cell
Frame Advantages
Certain parts of the interface (e.g., a TOC)
are always on the screen
Can avoid retyping common sections of
multiple Web pages
Consistent use across a large site
sometimes simplifies user navigation
A convenient way to mix text-oriented HTML
with Java applets
Image maps are more convenient if the map
image remains on screen and only the
results section changes
Frame Disadvantages
The meaning of the Back and Forward
buttons can be confusing
Poorly designed frames can get the user
lost
Hard to find real URL of a page you want
Printing problems!
Hard to bookmark "configuration"
Some very old browsers do not support
frames
Security
Hackers can insert frame cells into your pages in some
circumstances, perhaps stealing information intended for
your site
