-moz-border-right-colors

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.

Obsolete since Gecko 59 (Firefox 59 / Thunderbird 59 / SeaMonkey 2.56)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

In Mozilla applications like Firefox, the -moz-border-right-colors CSS property sets a list of colors for the right border.

/* Single <color> value */
-moz-border-right-colors: #f0f0f0;

/* Multiple <color> values */
-moz-border-right-colors: #f0f0f0 #a0a0a0 #505050 #000000;

/* Global values */
-moz-border-right-colors: inherit;
-moz-border-right-colors: initial;
-moz-border-right-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.

Initial value	`none`
Applies to	all elements
Inherited	no
Media	visual
Computed value	as specified
Animation type	discrete
Canonical order	the unique non-ambiguous order defined by the formal grammar

It does not apply

if border-style is dashed or dotted.
