Hi, VIPStephan. Thanks for your reply.
I've been doing a lot of looking around on Google for IE8 vs IE9 vs IE10, and I've seen a lot of complaints of how IE10 has been breaking the formatting of websites that render fine in IE8, IE9, FF, and Chrome. Not just personal sites, mind you; everything, including the Microsoft tech support pages, and some Microsoft blogs.
The app I am working on is used by many different organizations, each with their own internal network security settings and whatnot, which can make developing a bit of a pain, sometimes. The higher-ups just want to make sure that if/when an organization decides to upgrade all the browsers within their domain to IE10 that the app will render at least as close to how IE8 renders, if not exactly as IE8 renders. So I have volunteered to do research on any possible coding differences for IE10. Has anything in IE8 been deprecated in IE10? Has anything been added to IE10 that will work better than something similar in IE8?
And I know that all the Internet Explorer proponents will say "IE is DOM compliant, so code that works in FF or Chrome will work in IE", but that has rarely been my experience with IE. Seems like IE8 was slightly more DOM compliant than IE7; IE9 is slightly more DOM compliant than IE8, etc. Microsoft hasn't (for whatever reason) just gone as DOM compliant as FF/Chrome in one step; they are dragging it out, a little more with each iteration. They still (at least as far as IE8) have some proprietary CSS that only works in IE and nothing else. I think we've avoided that, but I've only been working on this app for a little over a month and have not seen every line of CSS, yet, so can't really say.
