问题 Navigation systems like the Garmin and TomTom have always fascinated me. I've wanted to implement small map/navigation applications to try out various pathing algorithms and expand on my knowledge of them. This is a two part question: 1.)

I even tried copying original code on SwiftUI update navigation bar title color, still not working.

问题 I am trying to make a css-only slide-out menu, which can be slid out and back, see my fiddle http://jsfiddle.net/EZ8SK/1/ here. Now I'd like to combine the Handlers into one.
