My company has 13 browsers (not including mobile/tablet) that it has to support. What I'd like to do is to take my list, one at a time, plug it into some kind of HTML5/CSS3 engine and have it spit out all of the tags/elements that I can use based on each browser.
If I had that I could then create a nice spreadsheet and come up with a strategic approach to what our HTML5/CSS3 strategy will be going forward.
I can't find any kind of functionality like this anywhere and I'm assuming it doesn't exist.
Anyone have any idea where I could do something similar? Even if there is manual labor involved, what is the best way to go about doing it?
Is this the kind of thing you're after? I think it's the reverse approach to what you're describing, but it might help.
That's basically what Modernizr does.
