We have done our best to design the CCMS Web site with all users in mind. This site was developed based on current standards and accessibility guidelines. This page and most others on this site comply with the XHTML Transitional and CSS2 markup standards as well as with the Section 508 and WAI Priority 1 accessibility guidelines. Compliance with XHTML and CSS2 is purely structural and can be easily confirmed by an automated check. WAI and Section 508 guidelines contain structural guidelines but also require consideration of the functionality of a document. Pages can be tested for markup compliance at the World Wide Web Consortium's markup validation web site and for accessibility at Watchfire's WebXACT accessibility tester.

Site Design

The CCMS Web site uses visual design to convey the sense of professionalism represented by the Center. Realizing that not everyone who uses this site will be able to access the content in this format we have chosen to present the design using CSS2. The reason for this choice is that the content of a page can be separated from the visual design of that page. Separation of content and visual design lets us maintain an underlying document structure that gives disabled users access to the information on a page. Separation of content from the visual design also allows changes to the look of the site without modification the content itself.

Web browsers that do not fully support CSS will still be able to use our site. Because the "look" of the content has been removed from the content itself, we designed the structure of an individual document to be accessible to all browsers.

If you're having trouble locating documents please try our site search or site map. If you are still unable to find a document you believe is located on this site feel free to contact us for help.
