Border Stroke Color

The border-stroke-color parameter defines the color used for the stroke when a border stroke is applied using border-stroke-size. This parameter must be used alongside border-stroke-size to produce a visible effect. Valid color values are a color keyword or 3- (RGB), 4- (ARGB) 6- (RRGGBB) or 8-digit (AARRGGBB) hexadecimal values. The “A” in a 4- or 8-digit hex value represents the color’s alpha transparency. The default is transparent white, 0FFF.
