18.2.2.4 Keeping headings together when other content intervenes

To keep sections from splitting into separate HTML files even when there is body content between headings that are assigned the Split property, you have two choices:

Prevent the content from affecting the split

Use alternative heading formats.

Prevent the content from affecting the split

To prevent a paragraph format (for example, ThinLine) that occurs between headings from interfering with keeping the headings together when SmartSplit=Yes:

[HTMLParaStyles]

; NoSplit prevents the para format from interfering with SmartSplit

; when it occurs between heads that would otherwise be kept together.

ThinLine = NoSplit

Use alternative heading formats

For the affected headings, consider using alternate paragraph formats with the same properties. For example, you could define a paragraph format named Heading1x and use that format instead of Heading1 wherever you want to prevent a Heading1 split.
