I'm not sure how you would do an iframe in CSS, but I don't think it's possible to do what you want anyway. Technically whatever's in the iframe is a separate html page- which means that the DDcode that automatically inserts the author's comments won't work. (The dd codes only work on the index page.) you'd have to type the comments in manually each time you wanted new ones. There's probably some other solution but I'm not sure what... sorry :[
That's true, Iframes wouldn't work. And the method for making comments scrollable (comments=400,200) doesn't work with Author comments because for some reason they only accept the width attribute and not the height.
You could possibly try Javascript. Here's one I was able to find here...
I'll try it out, it would be nice to leave my page as clutter free as possible, which is why I switched to a dhtml menu, and I love to gab :P
It worked, with some tinkering, fortunately I am the Tinker Queen. Thanks a lot guys, now I won't have to force the reader to scroll down a mile because of my chattering :P
