Generally, ePub files have two distinct tables of contents. One is nested with the document, and the other is merely a bookmark page inside the file, which lists all the entries to the table of contents available for readers to click on. ePub files bear a striking similarity to websites, since they both are made up of XHTML (Extensible HyperText Markup Language) codes, CSS (Cascading Style Sheets, a type of computer language used to display HTML or XML documents), and folders involving all pictures or links to these pictures. Hence, when you edit the table of contents of an ePub file, you need to edit the corresponding XHTML codes as well as the CSS for the bookmark links, just as what you have to do with a web page.
Currently there're a wide variety of ePub editors on the market. However, according to feedback from the users, quite a few of the editors have drawbacks that cause trouble.
