Welcome to WebmasterWorld, schyryll!

I believe that it is compatibile with IE4+ and Netscape 6+ and Opera 5+.

In other words, Netscape V4.x does not support iframes.

Then again, there are many threads in WebmasterWorld arguing the pros and cons of continuing to provide support for NN4.x vs not. And there are also threads arguing the pros and cons of using frames in general, let alone iframes.

AND just to complicate things, NN 6x makes you declare a specific height and width on the iframe so if you want a "fluid" layout, you'll have to do some fancy scripting. I've read all sorts of solutions to the NN 4x problem of not using frames, but the one I finally settled on was simply telling the users that if they want to see the site as intended, they need to upgrade (hint, hint). I then made all the content that would normally go in the iframe available to NN4x users via a new window. I simply put links between the opening and closing iframe tags with a target = "_blank". I've had no compliants. In a way, the start page acts as a remote menu for the rest of the site.

Another way to get Netscape 4 compatibility is to wrap <ilayer> tags inside your set of <iframe> tags.

NN4 ignores the iframe tags -- and modern browsers will ignore the ilayer tags, which were only specific to NN4.

However, you can't get scroll bars inside an ilayer, so you need to test your layout well.

<iframe SRC="foo.html">
<ilayer SRC="foo.html"></ilayer>
</iframe>
