>Description:
The Website has no dark mode

This would be implemented with a css media querry
>How-To-Repeat:
Visit the website with a browser that supports this functionality, like WebPositive, Firefox, Safari
>Fix:
Minimally, but missing quite a bit stuff:

:root {color-scheme: dark light;}

@media(prefers-color-scheme: dark) {
  body {
    background-color: Canvas;
    color: CanvasText;
  }
}
