Is it possible to make the border color a gradient? Or even to make 20% of the left border one color and the other 80% of the left border another color? I'd like to achieve it only with css not using images See image attached (left border mainly)
Umm I don't think so. you can make it so the left border is one color, top border is one color, etc etc. You will have to use a image.
You could do something like: background: url(myborder.gif) #000 bottom left no-repeat; so you use the image to act as the bottom part of the border and the colour for the top part.
