Thanks guys, .epub attachment with this.
I'm a complete newbie to all this so please be gentle, even though I've been typesetting for over 40 years and, yes, I was a hot metal compositor, how times have changed!
Problems with this so far:
1) Whenever I try to use a new tag <imprint> </imprint> Sigil reverts back to the <p> tag.
2) Using <I> tag Sigil drops in its own class tag. This is also true for centering text using the .center class.
3) The book cover displays correctly in Sigil/Calibre as does the Title page logo. However, Title page logo/colophon doesn't display at all in Adobe Digital Editions and shows as a very, very dark, almost black oblong on my iPhone. The cover pic. is fine in both Digital Editions and my phone.
4) I think this is a general issue with embedded fonts. Italics/Bold doesn't display in Sigil but seems fine on the iPhone and Digital Editions.
5) There's probably more but I've forgotten
Finally, could I use Dreamweaver CS4 to code up the text then drop it into Sigil.
Thanks in advance.
