As far as my knowledge extends, I don't think you can "close" frames and make them disappear. You could instead link to a page with a different frame set, where the frame you don't want no longer exists. Otherwise, you could use some Javascript. I don't know if Javascript works this way, i've never tried to use it with frames like this: <a href="#" onClick="javascript: document.myFrame.style.visibility='hidden';">Close</a> <frame src="blah.html" id="myFrame"> Code (markup): The code above in it's current state will not work. Period. But, if you do some research and modify a few things, it may work...
You should really read through that code before just ignoring it. There's actually very little Javascript involved, and the Javascript that IS involved, is very very simple. However, even if you don't know any Javascript, all you'll need to do is replace "myFrame" in "document.myFrame.style" with the name of your frame, and that should work. You'll also need to put id="whateveryourframeiscalled" in the <frame> tag. They'll have to have exactly the same names, it will be case sensitive.
