Funny how most websites between 2008-2012 where filled with bevel styling faking a sense of depth. Then 2012 onwards almost everyone started appreciating flat design. I wonder if the pixel density on displays played a role here. Flat design wouldn't look great on low pixel density but work brilliantly on retina displays. The opposite is probably true for beveled styling?
