How to turn off navigation styles in Big Medium's HTML preferences.
I want to use my own styles for the navigation. How do I get rid of Big Medium's built-in CSS navigation styles?
The Navigation panel of Big Medium's HTML preferences allows you to
select the style that Big Medium uses for its navigation bars, including
the "None" option to remove all styles. If you do this, the navigation
will consist of an unstyled <ul> list.
To make this change, select "Settings > HTML Preferences" and click "Navigation."
There are four separate settings that control the navigation styles: "Vertical style" and "Horizontal style" for the navigation widget and again for the subnavigation widget.
