-moz-border-bottom-colors

在Mozilla Firefox中, the -moz-border-bottom-colors CSS 属性的作用是给元素添加下边框的颜色。

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.

It does not apply

1. if border-style is dashed or dotted.
2. to tables with border-collapse: collapse.

/* Single <color> value */
