custom css help

Dear Kriesi,

please include some examples here: https://kriesi.at/documentation/enfold/add-custom-css/
This should solve many questions here and repeated queries.

– What is to do if the option: “Show element options for developers” turned on?
– What is to type in here and how is the declaration? “quick Css – Class. Add a custom css class for the element here. Make sure to only use allowed characters (latin characters, underscores, dashes and numbers)”
– How can i “talk” with the rules in the quick css box?
Some examples would be great e.g. to define a margin or shaddowsin nasted code.

Thanks
