Gradient borders

Question

I\'m trying to apply a gradient to a border, I thought it was as simple as doing this:

border-color: -moz-linear-gradient(top, #555555, #111111);
         


        

Answer 1

border-image-slice will extend a CSS border-image gradient

This (as I understand it) prevents the default slicing of the "image" into sections - without it, nothing appears if the border is on one side only, and if it's around the entire element four tiny gradients appear in each corner.

  border-bottom: 6px solid transparent;
  border-image: linear-gradient(to right, red , yellow);
  border-image-slice: 1;
