Change default font

[THaines]

So I'm being brave and trying out a bit of html (well, copying everyone else's!) and I've managed to create a gallery slideshow on one of my dashboards - very proud! 

Is there a way of setting the default font? I've found the way of setting the default text size but the ability to change the default font to Arial would be good too!

CSS font-family property is what I think you're looking for:

    font-family: "Times New Roman", Georgia, Serif;
