Full width responsive or adjustable width of the default Discourse theme

Is there any way to adjust the width of the default Discourse theme to be either full width responsive, or at least ~200px wider that the default?

You can add something like:

.wrap {
    max-width: 1600px;
}
.topic-body {
  min-width: 80%; 
}

To your theme in Customize >> Themes >> Edit CSS/HTML >> CSS

I’m using it with the Lite theme and looks way better
