Important guidance should remain usable in more than one way.
Designed for usable navigation
The site provides a skip-to-content link, semantic headings, visible keyboard focus, labelled form inputs, text-based error messages and reduced-motion support. Important technical explanations appear as text, not only inside images. Tables include headers and can be scrolled without forcing the whole page sideways.
Illustrative material images help identify formats but are not a substitute for the explanations. Selecting Mixed / Not sure lets you continue without knowing your exact format.
Tell us about a barrier
If a page or form is difficult to use, call (800) 477-0847. If possible, identify the page, the task you were attempting and the browser or assistive technology involved. We can discuss the project by phone if the online form does not work for you.
This statement is not a claim of independent accessibility certification or complete conformance with a particular standard. Accessibility is an ongoing responsibility as content and functionality change.
