Not sure if i was well understood.
I believed that Joop Laan wanted to build his own “preset style” and he would have liked to have it on the customizer drop down list.
I tried to add my “custom.css”, i forked the “lux.css” theme. After no need to override with the style.css of my child theme, i just need to edit the “custom.css” i made.
But with the things i detailed above, i can’t manage to have my “custom.css” in the dropdown list.
I don’t need to contact Bootswatch, since i need nothing from them. How do you populate the drop down list?
Thanks and sorry if i am too much lost ??
