Help changing font in text widget

I believe that you will need to do two things:

1. Add a span tag surrounding the text so that you can give it a class name. See the example below.
2. Add a CSS rule to the end of style.css to assign the desired font families.

The span example:

<span class='aboutme'>I am the mother of ...</span>

The CSS rule example:

span.aboutme { font-family: 'Kranky',arial,serif; }

Of course, you may want a different class name or fonts.
