Frames can vary in size from browser to browser. Although you can measure the height of a frame, setting it accurately to a desired and exact size is virtually impossible. MSIE is marginally better at this than Netscape.

Warnings:

• Height and width control of frames in Netscape is nothing less than a lottery. There are all kinds of platform dependent weirdness that crop up and you may find yourself doing a browser sniff and building in corrective document.writes() that fixes the frame sizes on the fly.

• Note that there is no width property to be able to measure the frame width value.
