Bootstrap 5 Dark ModeImproved in 5.0+

The following example assumes you're including necessary Bootstrap 5.3 JS and CSS as well as the data-bs-theme="dark" attribute to a parent element (such as html or an outer div tag). You can place the additional CSS and JS inside the formatting template or add to your site's CSS / JS files.

Dark Mode relies on features newly available in the Bootstrap 5.3 version in order to work.
