Thank you Chappie and Jeff. I decided to be brave and paste the CSS into my theme's css stylesheet editor (I use Parabola theme), and it did italicize all my text - thanks. What I wanted to do, though, was only italicize the body of the testimonial. My goal is to pretty much match the widget text characteristics with the characteristics of my testimonial page, specifically:
1. The actual testimonial is italicized, and the author's name is not.
2. Also, the font color of the actual testimonial is #993300, the author's name (and url if applicable) is black.
3. There is a space between the body of the testimonial and the author's name.
Jeff, I am not sure exactly what you meant when you asked me to paste in the content of one of my testimonials, "styling and all". Do you mean the text version, which includes the html? Thanks for your generous offer - if only I could figure it out! :=)
