For example, note that CSS files, once they're loaded, can @import
more CSS files, increasing the "needed to be loaded" count. Each time
you load a frame or iframe the mystery Amanda describes repeats.
Finally, JavaScript files can add any DOM nodes, including more CSS,
iframes, and JavaScript.
I don't mean to be discouraging. It might be a fun project to
implement some sort of progress bar -- for example, it could show the
load progress of each resource as they're discovered (see earlier in
the thread where you aren't guaranteed to know how long a given
resource is).
But if it were possible to make a progress bar that browser developers
thought would be meaningful, they would have been integrated into
browsers already.
