Hyphenation

The CSS hyphens property specifies how the words should be hyphenated when the paragraph text wraps on multiple lines.

The accepted values are:

manual

Words are only hyphenated when there are characters inside the word that explicitly suggest hyphenation opportunities. Those characters are:

U+2010 (HYPHEN): The "hard" hyphen character indicates a visible line break opportunity. The hyphen is always shown in the output.
U+00AD (SHY): An invisible "soft" hyphen. This character is not rendered visibly. It marks a breaking place for the word if hyphenation is necessary. You can use  in XML or  in HTML.

auto

Words are hyphenated automatically according to an algorithm that is driven by a hyphenation dictionary. Also, Oxygen PDF Chemistry uses an aggressive technique to create hyphenation points at underscores, dots, and case changes. This is useful when your publication contains snippets of code (Java, JS). To disable this functionality, you can use the -no-aggressive-hyphenation parameter.

Note: The element, or one of its parents, must have a lang or xml:lang attribute present for the processor to identify the hyphenation dictionary. If this is missing, the manual hyphenation is performed.

<table lang="en">
...
</table>

none

Currently not supported by Oxygen PDF Chemistry and it falls back to manual. If your document does not use the HYPHEN or SHY characters, no hyphenation is done.

Example: Hyphenation

To perform hyphenation on all paragraphs from an HTML document, you can use:

p {
  hyphens: auto;
}

Usually, it is best to activate hyphenation for elements that are known to have a limited width (for example, on tables) where long words could bleed off the page:

table {
  hyphens: auto;
}
