Re: Detecting browsers without transparency capability

[noahgelman]

I don’t think anyone uses a browser that’s too old to support rgba besides IE users.

No one uses pre- FF3+, Saf3+, Opera 10.10+

Anyone who uses FF, Safari, or Opera, updates often. Usually it’s done automatically for them.

Chrome has always supported it I believe. So really, all you need to worry about is IE. Using Modernizr is a bit over the top just for rgba support.
