CSS newbee here. I installed Calibre 30 min. ago to convert epub to pdf, but I kind of like epub in Calibre viewer.
Would you post the CSS code you use to make your viewer look the way it does?
I tried narrowing it with the tool in "configure" and tried http://www.w3schools.com/Css/default.asp
but nothing changed.
Seeing the correct code would go a long way in helping me understand how to do it.
