Apple Tutorial CSS not changing preview

Hi, just as the tittle says. I'm trying to follow the apple website tutorial and when changing the CSS property nothing happens (as contrary to what happens in the video at 2:46). This is a screenshot of my environment:

As you can see the background color of my navbar isn't changing to orange. Any ideas of what I'm doing wrong? I have bootstrap-studio v5.0.2

Thanks!

Ok I solved it. In the CSS property I have to add !important: background-color: orange !important; Otherwise the property is overridden by bootstrap.min.css. I don't know why though. Hope this helps someone

You shouldn't need to use !important unless it's been used somewhere previously in the CSS.

You have bg-dark chosen also for the background which does use !important. Set the background for the navbar to "default" and then you will not have to use !important on your orange.
