A font face is easy to fix, but when you change the font some fonts are really small at the default sizes of 10px and 8px...so it would be best if you would fix your layout (retrieve your CSS code from the source page), and with each item main text, link text, name text, etc... you could change the font and the size according to each.

I got this general code from a myspace support site.  myspace codes match JC faith only with the background code and the contact box code,  but text is different because of references.  Although I think because this code is basically generic (for the internet), it will work for you.

div body, td, li, p, div, textarea, li, h1, h2, p, br {font-family: vivaldi; size: 12pt ! important} 

12pt's is a good size..although the name and the top menu bar doesn't increase...I have no clue, but if you do each thing individually..you can fix that.

If you would like to know more could you message me, because it is very involved.  I don't want to type forever if you are not interested..LOL KWIM?

God bless you, I hope I have helped a little...It took me forever to figure it out (ask Greg and some others).  Although I have it mostly figured out,  it still baffles me at times.
