Flying Saucer Features h3(fs_heading){ clear: none }. Supported Features in CSS 2.1 Flying Saucer supports all of CSS 2.1 with a few exceptions. Consult the ${issue-tracker} for more information on what is not supported (in particular, the issues with a summary of "Support ...") or ask on the ${mailing-list}. If you do encounter a compliance bug or other unexpected behavior, please open a bug or post to the ${mailing-list}. Features: * 100% Java XML+CSS layout engine with Java2D (Swing) and native PDF output. SWT coming soon. * Strong support for the CSS 2.1 specification including extensions to better support paged media. * Good performance. * Support for XHTML including forms. * Arbitrary elements may be replaced with custom content. * Limited support for dynamic effects (for example, the :hover pseudo-class and links) * Some support for PDF specific features (for example, bookmarks and internal links). More coming soon. Limitations: * Resource loading is single threaded and occurs inline with layout. * Support for XHTML is weaker than XML+CSS (for example, not all XHTML presentational attributes are supported nor are X/HTML features like the <object> element). * No support for legacy HTML (although there are several open source Java HTML cleaners of varying quality available). * No support for incremental layout (applies to screen media only).
