I need to learn how to write HTML, CSS and JavaScript that will work regardless of operating system and web browser. For example,
Several web sites discuss the best approach to take. (They say that we should check whether browser objects contains needed features, instead of "browser sniffing".) But what I need is a checklist of all items that I need to check.
Does anyone know of a website that has a list of items (ex: event vs window.event) that I need to check?
Even with a site such as caniuse and using jQuery to remove most cross-browser issues, do you have to "code down" to support certain functions that don't work on browser X, but work on all other browsers??
I'm a server side guy trying to learn HTML5 and JavaScript2.0 and my limited JS experience (from about 3 years ago) has been that I had to do so.
Using jQuery, I cannot remember the last time I felt a need to do browser or feature detection. I'm not saying that it's 100% (can anything ever be?), but the likelihood of running into one of the exceptions is miniscule.
