I'm new to Custom CSS.
Listed below are the items of confusion I have in configuring my Newsletter Opt-In box.
1) I can't figure out which lines of code refer to which elements of the MAB. Because of this, I'm unable to...
1a) Use a font which is unavailable in the drop-down menu.
1b) Center-align the Submit button
2) Which Custom CSS box should I be editing? In a particular MAB Settings or in the particular User Style?
3) What is the code to have a field label placed inside the text input field instead of above it?
Thanks for your help and patience.
