A new theme required some changes in the base HTML template and all CSS themes. The new theme is called "hellpastell", which means "bright pastel"
I have removed the javascript function for light and dark site layout and created 3 new themes which are dark. It should now also be possible to remove the theme cookie.
The Inktober pictures are somehow too many (58) and don't fit in here.. so they will be removed and put on another site --> https://ideenlos.org
update: done (removed)
update 20230909: some added again
