[Plugin: Testimonials Widget] CSS – Author in different line

I used the shortcode to list the testimonials on a page. it works fine so far. I am just trying to get the Author and Source on different line. But it sems there is a comma “,” that gets inserted after Author which gets pushed to a new line if I use the diplay:block; my code is:

.testimonialswidget_author{
font-style:normal;
color: black;
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
display:block;
}

But when I do this my entry is displayed like this:
I loved the products, will be ordering more on a regular basis!

How do I get this corrected, I tried finding before posting but it was driving me nuts so gave in and asked for help.

Also, I cannot get the quotation marks to work. We are only supposed to Uncomment the block if we do NOT want quotation marks. So I left it as is because i DO want them, but they do not get displayed.

Help!
