Change font and size on Slider Property Control

Good afternoon!

I have inserted a slider property control into a text area on my page.  When I right click on the box in Edit Text mode and go to "Format Control", the font, size and color selection boxes are all grayed out and I am unable to change the defaults.  It is not visually appealing to have the values above the slider bars be a different font than the rest of the text in the text area.  

Thank you very much!
