Section Features Supported on HTML Export
Each section is exported as separate <div> elements as a child of <body> when there is more than one section in the document.
If there is only one section then the document content is exported directly to <body>.
Section-wide formatting is exported as CSS styles on <div>.

Headers and Footers
There is a save option that controls how headers and footers are output. This controls how the primary header is exported in different places in the output document.
By default, the header of the first section is exported at the top of the HTML output and the last footer of the last section is output at the end of the HTML output. Any linked headers and footers are taken into account.
When embedded or external style sheet is set, regular paragraphs in the header or footer are exported with “Header” or “Footer” style.
See the following link in the documentation for further information:
- HtmlSaveOptions.ExportHeadersFootersMode

Section Break Type
Section breaks are exported as a <br> tag which contains the special Microsoft Office attribute mso-break-type:section-break.
There is an option to skip exporting breaks to HTML at all.
Note that when exporting to EPUB such break elements are normally ignored by most EPUB readers. Instead, use the DocumentSplit option to split the internal HTML of the EPUB at each page break. This will appear correctly in almost all readers.
See the following links in the documentation for further information:
- Section.SectionStart
- DocumentBuilder.InsertBreak
- HtmlSaveOptions.DocumentSplitCritera

Page Margins
Page settings are output optionally to HTML through the use of a save option. This is exported either as an embedded or external style sheet depending on the save option used.
Section formatting is exported using the “@page” identifier along with margin and size attributes that define the appearance of the section as seen in the source document.
Some features need Microsoft Office specific attributes, they are not currently supported.
