Erik, none of those work. They just turn the outer portion of the nav bar from white to a light purple. I want the main portion of the nav bar to be two toned to give it some depth.
I add the CSS with my Simple Custom CSS plugin. I achieved the effect on another site by using the Max Mega Menu plugin, but I’d rather do it with CSS. Here is the site: https://www.designhous.com
Yes, but as a test I removed all my nav bar code and just added each of your code suggestions. Each time, the result was a wider nav bar with only one solid color.
