Argh
disappointment! My solution is flawed in that the size of an em-space varies from font to font, and Kindle indents by em-spaces. Therefore, the size of a 4em indent is unpredictable. If the reader changes fonts, the alignment in my solution gets zonked.
I heard someone say "The more I work with Mobi, the more I like Epub." I'm really feeling the same way.
But let us (me) not turn this into a Mobi-bashing session.
Anybody got a solution that works more widely than just for the Kindle 3 default typeface?
