The problem was me - I have made some progress by starting my CSS again - now getting some colour in text and table backgrounds using classes but finding it frustrating that apps read the code differently. EG FB reader does not show my sans serif font (or any sans serif font) and the others do, a link to another page attached to a graphic sometimes works and sometimes does not, and in IBooks display=inline block is ignored. Even photos are split across screens. My client is reluctant to specify a platform so I guess they will have to live with the differences in appearance between reader apps. (We are looking at Androids or Ipods mostly - Nooks and Kindle Fire are not available here)
Can anyone suggest how to hide a number of pages (chapter) from appearing in the TOC or navigation options? I have tried setting the spine settings to linear = NO whereupon other pages are not available.
Also cannot get anchors to work reliably in anything (Mantano, FB Reader, Galaxy Ebook, Ibooks)...
