if you mean by “the tag cloud” the tag associated with specific posts,
Sorry, I meant only the tag cloud widget on the index, I should have said this, but I just saw this is easily manageable with Tooltipy Pro too.
For me as a native german speaker I saw not a difference between Kategorien und Familie in my case, but yes, sure – maybe it’s important for other wordpress sites, sorry this was my fault.
Thank you for your time answering my questions and this great add on of course! The css-solution worked well!
Have a nice day.
