Please somebody, explain to me how to create an effect like that. I've tried everything inset shadow,opacity,gradient,masking.
I'd like to design to my slider a same background as the arrows (next/prev) have on this website : uchicago.edu
Those slider arrows are nothing more than white marks on a transparent background (denoted by the checkerboard pattern) and saved for web as PNG with transparency. See Twitter Icon example below.
