This is an example of a paragraph that is aligned in the center of the page. In XHTML Transitional you could use the attribute of align="center", but that will not validate as XHTML 1.1. Instead I needed to create a CSS class that had align: center; and applied that class to this paragraph.
What the W3C says about XHTML:
This document type is essentially a reformulation of XHTML 1.0 Strict using XHTML Modules. This means that many facilities available in other XHTML Family document types (e.g., XHTML Frames) are not available in this document type. These other facilities are available through modules defined in Modularization of XHTML, and document authors are free to define document types based upon XHTML 1.1 that use these facilities. It is an example of a larger build of the modules from the Modularization of XHTML, avoiding many of the presentation features. While XHTML 1.1 looks very similar to XHTML 1.0 Strict, it is designed to serve as the basis for future extended XHTML Family document types, and its modular design makes it easier to add other modules as needed or integrate itself into other markup languages.
