Hi Guys!
I have just formatted my forst epub in Sigil, it is a great program I can say

1. I have a couple of things I dont get, where can I check the default style sheet (if I do not add a new one to styles) and modify it?
2. where could I get a full style css with all of the parameters which are necessary for a html section?
3. how could I insert page breaks inside chapters?
Thx
Cheers
