Q: How can I use Sass to style the top bar dropdown menu divider? How can I use Sass to style the TopBar dropdown menu divider (shown as a black line in the image below)?
This portion in _setting.scss only seems to apply to the vertical menu dividers:
// Divider Styles
$topbar-divider-border-bottom: solid 1px scale-color($topbar-bg-color, lightness: 13%);
$topbar-divider-border-top: solid 1px scale-color($topbar-bg-color, lightness: -50%);



A: The code below are just sass variables that are being used for the style of the divider.
// Divider Styles
$topbar-divider-border-bottom: solid 1px scale-color($topbar-bg-color, lightness: 13%);
$topbar-divider-border-top: solid 1px scale-color($topbar-bg-color, lightness: -50%);

You'll need to find where the actual class '.divider' is being defined and update the styles there.
