Add Space between Title and Author

Hi Folks,

I am trying to get a space between the Title and Author.

My current code is:

<div>
<div style="line-height: 2.5em;">[catlist name=(christian-testimonies) orderby=title order=asc numberposts=300 author=yes title_tag=b]</div>
</div>

Regards and thanks,
Angus
