Recently a friend asked me how to make a gradient border on a button. I really am not a fan of gradients, but some clients love that crap.

See the Pen Button with Gradient Border by Felipe Nunes (@willpower) on CodePen.

He asked me to make a SASS Mixin too, but if you change the $color_base to other color value, I think it works 😛 One of the wonders of SASS.
