Accessibility Help (Page 3 of 4)

Level-1 Pages

Each Level-1 page contains menu-style links along the right of the page, with footer links located at the bottom of the page. All images are accompanied by Alt-attribute descriptions.

At the very top of the page are three links: one to the content of the Level-1 page; one to the Accessibility-Help Page (structural description and access instructions); and one to the footer.

Level-2 Pages

Each Level-2 page includes narrative content and, where possible, a text link back to its primary reference page.

Level-3 Pages

Each Level-3 page provides an external link to content that exists outside of the website. Users should click on the browser's back button to return to the web page. Navigation features within Level-3 web pages may significantly differ from the website.
