The text in the Retry Payment button runs outside the edges of the button.  Is it possible to increase the size of the button so the text will fit?

I don't need the Affiliate and Extras information in the footer and I want to remove it without modifying Footer.cshtml.  I see there is a place to add custom css styles (Custom Head Styles).  Can I add some css code here to get the result I am looking for?  If so, what do I need to add?
