@SNEATED it depends on what reasonable solution is
The slideshow and the banner might be using the same CSS classes (“banner__media”). This would unintentionally cause the slideshow to behave like the banner. You could add a new class to the banner section and use it as a new selector for the banner customization.
E.G: In the banner section, you can add (append) a class “custom__media” and replace in the CSS code “banner__media” with “custom__media”.
