Flying Saucer Features

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).
