In looking at purchased reponsive template code from a third party, I see all kinds of issues. This thing looks like a web designer tried to write an email template. Which is what we're all really doing, I suppose. There are @font-face src: url, animation, CSS hovers. Am I being too conservative? Can some of these things work? I heard the hover hack using the <html lang> declaration on #emaildesignpodcast. But I can't use something like that for this audience. I need to be super sensitive to ADA best practices. Who's got some advice for me?
