CAST is committed to ensuring that its sites are accessible to all users. If you encounter a problem accessing cast.org or would like to provide feedback, please email firstname.lastname@example.org. These guidelines are based on federal requirements outlined in Section 508 (the "Electronic and Information Technology Accessibility Standards," authorized by the Architectural and Transportation Barriers Compliance Board) as well as the Web Content Accessibility Guidelines version 2 (WCAG2) recommendations of the World Wide Web Consortium (W3C).
The CAST sites have been designed with existing accessibility recommendations and standards in mind. To ensure complete accessibility to all users, these sites have all global navigation exposed. High-contrast dark text on a light background is used for better readability.
Images on these sites, unless they are purely decorative, are accompanied by text alternatives (the "alt" attribute) that identifies the image or its function. If you are using a graphic browser, alt-text tags are visible only if the browser's automatic image-loading feature is turned off.
Text hyperlinks are written so that they make sense when read out of context.
Where tables are used for the presentation of data, table cells are associated with headers to facilitate navigation with screen readers. Also, each data table has a summary that provides additional information about the table's contents.
Each page on the CAST sites begin with a "skip navigation" link. Choosing this link moves the user directly to the main content of the page, bypassing the long list of navigational links which appears on every page. This permits faster and easier navigation for those using screen readers or for anyone using the keyboard rather than a mouse to navigate the site.
