This issue seems to have reared it’s ugly head again in recent times. There always were problems years gone by with Internet Explorer and the other browsers, but more recently I have found great differences in Mozilla and Chrome. I have revisited an old site that’s just HTML with a few minor JavaScript additions. Mozilla fails to display two pages that chrome can display and vice versa on the two remaining pages. I will be checking the code later, to see exactly what creates the problem. However, I was really hoping that the days of writing separate CSS for browsers would eventually be behind us.
