The PmWiki.Wiki Styles introduction states:
It does this by applying stylistic attributes to the HTML tags generated during markup translation, which the reader’s Web browser then interprets.
Wikipublisher aims to honour the author’s stylistic intentions, but is constrained by what the typesetting engine can do and the intrinsic differences between print and Web. A style that is appropriate for a Web page may not be appropriate for print. The engine detects all applied styles and converts those it understands to their print equivalents, ignoring those it doesn’t understand. The following table summarise the status of style support in wikipublisher-2.2.39 (Wednesday, 25 April 2012).
Wikipublisher style support
center text right-align text text color text background color division color division background color division frames comment
block background color (treated as text background color)
text floats list bullet/number styles
figure frames (sidecaps makes this hard) external CSS styles table styles any other attributes
If there is a style that you think Wikipublisher ought to support, either raise an issue or contact the wikipublisher project. If you have pages that make heavy use of styles, be sure to test the typeset versions for unexpected or undesirable behaviour.
