// Justified navigation
//
// Justified nav components are only built for flexbox mode in Bootstrap 4. In
// previous versions, this component variation was limited to anchor-based nav
// implementations--meaning it couldn't be used on button elements. This is due
// to a longstanding Safari bug in responsive table styles.
//
// Using flexbox, we avoid that problem altogether at the cost of no default
// justified navigation for default Bootstrap. Sorry, y'all <3.
