Just a note in case it helps:
When developing a site I often put additional css stuff in the Actinic/Sellerdeck style sheet so it is easily accessible in design view,(I do use separate style sheets too.)
Bringing a complicated v11 site into v12 it imported OK but my additional css was stripped out of the Actinic stylesheet and had to be replaced manually.
