Custom Hotbar Font Change?

[FloridaFringe]

Hello.

I'm wanting to use a custom hotbar but am having trouble with the size of the fonts for the one that I've chosen. Would anyone be will to help make this change or to help explain in simple terms how it can be done? Everything else about this particular UI mod is exactly what I'm looking for except having a smaller font would be ideal.

Any help is greatly appreciated. Thanks.
