Me too, or was it NCSA Mosaic in 1994?  I thought I'd never abandon
Lynx, but I switched to Mozilla in the 1.x days.

I only learned about CSS some 6 years ago.  You have to be a little careful
if you want to support very old browsers, such as Netscape Navigator 4 or
Microsoft Internet Explorer 4.  I got Netscape 4 to crash on validated HTML
and CSS (I had defined margin, padding, or border for the BODY element IIRC),
and the content was often illegible.  With some testing, it was possible to
get readable layout on the old browsers.  But I guess it is reasonable
to assume that nobody is using Netscape 4 or MSIE 4 in these days.  It should
be sufficient to test with Mozilla Firefox 1.x, 2.x, Konqueror (or Safari),
Opera, MSIE 5, MSIE 6, and MSIE 7.

Right, that was what I meant.

You're welcome.  Thanks for your effort!  And please let me know if you
need assistance with the HTML code generator.  I'm currently a
housefather, until my kids will start in the kindergarten in August.
So I have some spare brain capacity left for simple coding. :-)
