When I try viewing it in Mozilla/Netscape....then I see hyperlinks in different colors which then change once they have been visited. Is there anything wrong with the (very simple) syntax?
testing on ie6 and moz 1.3 i dont see any diff. in the color or link behavior. Do you maybe have other rules in your css that maybe interfering?
are Mozilla/Netscape different browsers or in effect identical?
The short version is that they react (almost) identical in the newest version beacuse they are both using the Gecko-engine, the codebase or the algorithm of the browser. Check the versionnr in help/about in the browser an you will see Gecko ver. nr.
Maybe sombody could point to a more elaborate explanation of why this is so?
The only difference I cannot resolve between IE and Mozilla/Netscape is cell borders. I want to see black bordes around some cells and they appear fine in IE but not Mozilla/Netscape, where instead no border is shown at all.
