If am writing a local app that will only run using a specific browser, am i setting my self up by slightly ignoring W3C’s standards? I ask this question because in this app i am thinking of using custom HTML tags, custom attributes, etc…
Thanks in advance guys.
I believe you should follow the standards. The reason is that technology evolves, but standards usually stays for a while.
Consider that a new version of the browser might not support what you are trying to do in the future. Do not believe people will stay with a certain version of a browser just to use a website. People might be obligated to change version for security reasons. Have you heard about the Aurora IE Exploit.
Here are some links about the exploit:

Also, take into consideration that the standards are meant to make everyone’s job easier and everyone will understand the same thing. I believe that web developers should make content viewable and useable for as many people as possible and for as many browsers as possible. Have a look at the W3C mission.
