I forgot to mention the last property, Merge Position – Top.
Here’s the relevant pages as well:
http://www.foundwonders.com/ (note smaller text on the right compared to my test on the left)
http://www.foundwonders.com/about/ (where CAS replaced right side)
Well here are the properties: Exposure-Singular, Handle-Replace Primary Sidebar.
To clarify, the .textwidget CSS works just for the Primary sidebar. I tested a new one in the Secondary sidebar and the text is unmodified just like the CAS-created sidebar.
Thanks for your help.
Sorry about that, it’s the Prose theme for the Genesis framework. I do know about the studiopress forums, but thought it wouldn’t hurt to try here since the response to my last query there was rather tepid.
