There are no sections in EPUB or XHTML. As I understand, you mean "flow breaks".
Flow breaks are created by dividing the eBook contents into separate HTML files. If you have 10 HTMLs in your EPUB package, there will be 9 flow breaks (or hard page breaks) in your eBook (when viewed in eReaders).
The rule is very simple: Atlantis creates as many flow breaks in EPUB as hard page breaks in the source document.
Continuous section breaks do not create page breaks, otherwise they would not be named "continuous".
There are multiple ways to create hard page breaks in a source document:
1. (Hard/manual) page breaks can be created by pressing Ctrl+Enter (inserts a manual page break symbol), or by inserting non-continuous section breaks (the "Insert | Break | Section Break" menu).
2. When you have a "zoomed to fit page" image in your document, Atlantis also implicitly adds page breaks before and/or after it. Double-click a picture in your document to toggle the "zoom to fit page" option for this picture.
3. You can also create a page break before a paragraph by enabling the "Page break before" attribute on the "Line & Page Breaks" tab of the "Format | Paragraph..." dialog for this paragraph. Quite often this attribute is enabled in the "Heading 1" style. In this way, each chapter automatically starts at a new page.
By the way, this method is preferable over the "Ctrl+Enter" method – please click the below links for details:
