Hello Hitch,
Just wanted to let you know your assistance has really helped.
I have been successful in getting two fonts embedded and working in HTML and even built into a .mobi file using Kindlegen that appears okay on Kindle for PC.
I still have problems applying indents and other classes to the embedded fonts in HTML. Doubling up on classes (class="embeddedfont indent") kills the embedded font, and applying additional styling classes to a <span> tag (as you did in your example) does nothing. I'm disappointed that applying <div class="embeddedfont> doesn't apply the font to the whole division so that other styling classes can be attached to subordinate tags.
Do you have any advice?
Tony
