> I think it is important for design/dev to have a mutual understanding of one another, but I don't think you can truly be a great designer and great developer in one. Having an understanding of the other perspective is important. You'll never meet a surgeon who specialises in brain and heart surgery, why should design and development be any different?

What is the definition of "developer" here? Does it include HTML and CSS? I love working with designers who can translate their designs into actual layout and styling because it seems a lot closer to what they're good at than it is to what I'm good at. It seems like there's quite a bit of gray area in these definitions, but building front-end application behavior seems to flex similar muscles as building back-end application behavior, while tweaking CSS seems to flex similar muscles as tweaking element widths in photoshop. I'm genuinely curious what the common designer point of view is on this!
