Collapse-O-Matic is a WordPress plugin that removes clutter and saves space. Display and hide additional content in a SEO friendly way by wrapping content in an [expand] shortcode.
This simply adds a "None" style option which doesn't load any styles. Of course, it's then incumbent upon users to handle the styling (whether that's simply integrating light_style.css or dark_style.css into their theme's stylesheet or doing something more involved). I'm personally using this to style things myself while also getting rid of a request (since the styling is part of the theme's stylesheet).
