The metallic finish is just an image, "for CSS" made me think this used only CSS to achieve the effect. The use of `filter` make it look nicer but other than that there's not much original here. Maybe try abusing nested borders, gradients and shadows until you can achieve the same thing with CSS alone. The JS to render the image blob is creative. Also elements with a fixed height (or `line-height`) get tricky with dynamic content, linebreaks, etc. Maybe find a way around that. (Cool demo, thanks for sharing)
