A new version of my Rediggit theme for Lemmy has dropped, and with it comes a name change...
Rediggit is now Lemonberry, to better reflect the separation from Reddit.
I've also added a much-requested dark mode, adapted from Lemmy's default darkly theme. Those familiar with the Reddit Enhancement Suite's dark mode should find this pretty comfortable.
The latest version of Lemonberry is optimized for Lemmy v0.18.1 only and is available on GitHub and UserStyles. I will likely keep the optimizations in sync with only the larger instances as Lemmy development is changing rapidly, and it's proving difficult to maintain compatibility with older versions.
You can also find older versions of the theme, and additional screenshots, at the GitHub repo.
If you have no idea what any of this means, Lemonberry is a flexible, full-width light and dark theme for Lemmy. It is just one of many user-made themes for this community. These themes can be installed and enabled with the use of a CSS injector browser add-on, such as Stylus (Firefox, Chrome). UserStyles.world is a good place to start exploring the available themes.

So it's something the admins of my Lemmy instance apply, and everyone on that instance gets?
No, but that might occur in the future. For now, it's just a user-side style.
The links to Stylus and userstyles.world in my original post should be enough to get you started. There are many other themes available for Lemmy there, and for other sites too, such as reddit, Wikipedia, etc.
Other, similar browser add-ons exist too, such as Stylish and Stylebot, but I don't have any experience with those.
Edit: sorry, I think I misinterpreted your question. Technically, yes any instance admin could adapt this style for native use on Lemmy and then make it available to its users, but both Lemmy and my theme are changing daily and they would need to update it with each and every change. This why we ultimately stopped doing this for lemmy.ca.
