Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
In Mozilla applications like Firefox, the -moz-border-top-colors
CSS property sets a list of colors for the top border.
/* Single <color> value */ -moz-border-top-colors: #f0f0f0; /* Multiple <color> values */ -moz-border-top-colors: #f0f0f0 #a0a0a0 #505050 #000000; /* Global values */ -moz-border-top-colors: inherit; -moz-border-top-colors: initial; -moz-border-top-colors: unset;
When an element has a border that is larger than a single CSS pixel, each line of pixels uses the next color specified in this property, from the outside in. This eliminates the need for nested boxes. If the border is wider than the number of specified colors, the remaining part of the border is the innermost color specified.
