+      What's going on here?
+      I want to make it easy for admins to style this application. To have
+      a good set of default themes, I chose the system from base16
+      (https://chriskempson.github.io/base16/) to style all elements. They
+      all have the base00..0F classes. So the only thing an admin needs to
+      do to style Pleroma is to change these colors in that one css file.
+      Some default things (body text color, link color) need to be set dy-
+      namically, so this is done here by waiting for the stylesheet to be
+      loaded and then creating an element with the respective classes.
+
+      It is a bit weird, but should make life for admins somewhat easier.
