You know what? Creating this blog got me into a new features spree.
Dark Mode Switch for Drupal is a feature that I have been longing for since Mac Os got Dark Mode.
It is exactly the same feature I have used on the top of this very drupaloid site.
All you gotta do is enable the module and put the module block into a region of your choice, then, you can copy its template file and customize the Toggle Element as you wish.
Hope you like it!
