If Internet Explorer and Netscape browsers were identical, scriptwriters would be saved a lot of worry. With increased support for standards, the differences when scripting basic tasks are becoming smaller and smaller, but still one has to be wary. Here we review versions and discuss strategies for handling differences.
Mainstream Browser Version Review
A mainstream browser is just one with a big share of the market. At August 1999, choosing a mainstream browser means choosing between Internet Explorer 4.0 or 5.0 and Netscape Navigator or Communicator 4.0 or 4.5 or 4.6. According to the Mozilla Website, version 5.0 of the Mozilla browser, which is Communicator 5.0, will be released around the end of 1999.
Navigator and Communicator Versions
With this release, Netscape started to slip behind Internet Explorer in functionality. The way the browser processed HTML made it hard for the Netscape programmers to provide full support for Dynamic HTML, and an unusual processing innovation in the event model failed to take off. Version 5.0 removes both these obstacles. The tiny increments in version, such as 4.01 and 4.02 mostly reflect security fixes that forced a new browser release.
4.0 and 4.x versions continue to be released in minor versions that contain bug fixes only - at the time of writing 4.08 and 4.61 are the latest versions.
Internet Explorer Versions
The event model in IE 4.0 has been adopted by the Web standards body, W3C for the DOM - the Document Object Model Standard. Other features of IE4.0 also influenced standards such as HTML 4.0 and related stylesheet standards.
