provide a webkit equivalent for -moz-border-*-colors (multiple border colors)

• Component: CSS
• Status: RESOLVED CONFIGURATION CHANGED

hi, some months ago I've suggested to include multiple borders in the css3 spec without success

i think that to use XBL for multiple borders is absolutely stressful 

in Mozilla XUL's style these properties are used frequently

-moz-border-top-colors:;
-moz-border-left-colors:;
-moz-border-right-colors:;
-moz-border-bottom-colors:;

to define multiple border colors for widgets

and flexbox web app are coming, and I'm in one team that is developing a next generation web gui framework,
so, for parity, i hope to see this (or better implementations) in Webkit,
all the alternative solutions (border-image, xbl) are crazy to use just for borders

thank you for your work! greetings from italy

an interesting solution can be use box shadows

but with rgba and hsla colors outer shadow color is mixed with the inner shadow color

test this:

<style>
.test
{
-webkit-box-shadow:
0 0 0 10px rgba(255,0,0,0.5)
,
0 0 0 20px rgba(0,255,0,0.5)
;
margin:30px;
}
</style>
<div class="test">test</div>

inner shadow (red) is mixed with the outer shadow color (green)

so in the box-shadow property can provide a way to set the outset position of the shadow

for example...

-webkit-box-shadow:
0 0 0 10px rgba(255,0,0,0.5)
,
0 0 0 10px [10px 10px 10px 10px] rgba(0,255,0,0.5)
;

or box-shadow can provide a way to enable and disabled the blending

box-shadow-blend:true||false

Based on following - https://caniuse.com/?search=border-color

Webkit / Safari do support CSS3 property "border-color" except Mozilla's non-standard one and I can test it on below link:

https://developer.mozilla.org/en-US/docs/Web/CSS/border-color


Although on CSS3test.com, it does not show as "Green" (highlighting support).

Web Spec link - https://www.w3.org/TR/css-backgrounds-3/#propdef-border-color

Considering MDN demo and CANIUSE confirm that Webkit/Safari support standard specific "border-color" property, I think this can be closed as "RESOLVED INVALID" or "RESOLVED DUPLICATE OF XYZ". Thanks!

We definitely support border-color.
