Not sure what you mean by "advance technology", but I'm guessing you mean "a technology capable of handling more complex scenarios than can easily be done with HTML and Javascript". You might be looking for:
- jQuery (a Javascript library)
- ASP.Net (a client-server architecture)
- Silverlight (RIA plugin)
- Flash (RIA plugin)
- Visual Studio (Web-capable IDE)
If none of that is what you are looking for, you might consider phrasing your questions better.
