The Issue
Just to give you some background, I'm currently enrolled as a student at the University of Mary Hardin-Baylor. Currently the web design classes there are somewhat... sub-par. My DHTML teacher worked on websites in the Netscape/IE clash and most of the stuff he teaches is deprecated, non-semantic HTML, or inline code. He is still a huge supporter of IE and is still avid about students learning IE filters. From what I've seen he seems to see no need to support multiple browsers. I'd really like to see the web design section of the school grow and as long as the teachers are still teaching deprecated code, it probably won't. I'm planning on sending him an e-mail trying to convince him to drop the IE filters section of the course next semester and replace it with something that students will actually be able to use cross-browser.
The Request
I need help building my argument.
- I need to build a list of reasons on why filters are deprecated and shouldn't be used(I believe they aren't even supported in IE9 anymore).
- It might also be advantageous to give reasons why cross-browser support should be achieved.
- I need some reputable sources that I can quote. This excludes sites like wikipedia.
Also, on a side note, one of the reasons I'm asking this here is because I don't have any type of real world coding experience. If I had support from someone else who worked in the same era of the web, it could do wonders for the legitimacy of my argument. I don't want this to sound like I'm just bashing his methods, or even worse... just trying to get out of work.
Thank you in advance for any help you post! I know this is a huge request. I appreciate any time your willing to give.
Edit
I just wanted to point out that I agree with some of the comments made. The filters section of the course is a very minor problem. There is a numerous amount of other issues that woul
