 ## Navbar

-After the hero image has scrolled past the navbar, the navbar's (opaque)
-background color is set -- usually to the site's [primary color][].

-The text of navbar entries can be difficult to read with some hero images. In

-`params.ui.navbar_translucent_over_cover_disable` option to `true` in your
-site's [configuration file][].

+background.

+To enable the display of a Light/[Dark mode] menu in the navbar, set
