libRocket has no prior understanding of XML elements other than the built-in element types.

When parsing a tag libRocket will look up custom elements associated with the tag name and fall back to a generic element. Very few custom elements are required as most of the power in libRocket comes from styling elements with RCSS to produce the desired layout.

The user is encouraged to follow standard HTML guidelines where possible to improve readability across the community. For more information on setting up libRocket to emulate HTML4 see Appendix: HTML4 Style Sheet.

id = id (CS)

style = cdata (CS)
Specifies inline style information for the element. See RCSS.
on* events = cdata (CS)
Event bindings. See Events.
