The trend these days has been away from browser detection, and towards feature-support detection.

Google has some Javascript code to detect Flash support (as do others, but this is a decent example):

is it possible to only change the DIV n not the whole page

Absolutely, this is pretty standard javascript stuff. There are a million different ways to do this. If you're using jQuery, I'd start by looking at some of the DOM manipulation functions: http://api.jquery.com/category/manipulation/ and going from there. Of course, this is easily possible without jQuery or any other JS framework. But that seems like it's beyond the scope of this question.
