Custom Default Font

How exactly do you set a default font for the textarea to a custom font?

I have googled and tried pretty much every suggestion and I cannot get it to work.

I currently have:

CKEDITOR.config.contentsCss = 'myfonts.css';

CKEDITOR.config.font_names = 'myFont;'+CKEDITOR.config.font_names;

CKEDITOR.config.extraCss += "body{font-family:'myFont';}";

Where fonts.css has the @font-face bits.

I have also change this in contents.css body selector:

font-family: 'myFont';

This still does not change the default font of the textarea.

Note: The 'myFont' font DOES work. It is selectable in the drop down and does update the text selected and works properly . What I need is for an empty textarea to use this font by default.

Any ideas?
Thanks.
