I'm testing another 'kind' of CSS-file for changing fonts:

There is a CSS-file from PRS+ named 'FontsAsInLRF.css' with this code:

@font-face
{
	font-family: sans-serif;
	src:url(res:///opt/sony/ebook/FONT/tt0003m_.ttf);
}
@font-face
{
	font-family: serif;
	src:url(res:///opt/sony/ebook/FONT/tt0011m_.ttf);
}
@font-face
{
	font-family: monospace;
	src:url(res:///opt/sony/ebook/FONT/tt0419m_.ttf);
}

It forces to use the standard-fonts of Sony instead of the defined fonts of the ebook. Using the principle of this file I produce CSS-files like this for other fonts (like Caecilia in this case):

@font-face {
  font-family: serif; 
  font-weight: normal; 
  font-style: normal; 
  src: url(res:///Data/fonts/CaeciliaLTStd-Roman.ttf); 
}

@font-face {
  font-family: serif; 
  font-weight: bold; 
  font-style: normal; 
  src: url(res:///Data/fonts/CaeciliaLTStd-Bold.ttf); 
}

@font-face {
  font-family: serif; 
  font-weight: normal; 
  font-style: italic; 
  src: url(res:///Data/fonts/CaeciliaLTStd-Italic.ttf); 
}

@font-face {
  font-family: serif; 
  font-weight: bold; 
  font-style: italic; 
  src: url(res:///Data/fonts/CaeciliaLTStd-BoldItalic.ttf);

(complete code)

If there is just ONE font for normal, bold and italic, CSS-file looks like this:

@font-face {
  font-family: serif; 
  src: url(res:///Data/fonts/CaeciliaLTStd-Roman.ttf); 
}

That's the complete code inside the CSS-file. Very simple... and seems to work. Of course just fonts, not size nor line-space is altered.
