Nope, already tried that.
Actually, I uploaded the site with the custom css already working locally (still works –locallly–), but online, it doesn’t.
Tried it in different browsers. Is just like the custome css doesn’t exist at all.
I must say I am not at all savvy in this matter, is my first time using Publii (loved it!) and english is not my native language.
Thanks for your help, in advance!
