How to Format Font Size and Color for Masked Input Widget?

I need to use the Masked Input widget to get the currency formatting, but I also want to change the size of the font and its color.  Is there a way to do that?  If it's by injecting CSS code, could you possibly give me the css code to use?  I don't know CSS.

Hi!

You are right, for advanced styling, you would need to inject CSS code into widget. Can you provide us exact requirements so we checked for possible code for you? Also, what is the form you are working on?
