We want everyone to be able to use this site, including people who rely on screen readers, keyboard navigation, magnification or other assistive technology. This page describes what we have done, what we know is imperfect and how to tell us about a problem.
Our target
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA, published by the W3C.
What the site does
- Body text starts at 18 pixels, with high-contrast colors chosen for readability.
- Buttons and links are large enough to tap easily, and the call button stays within reach on phones.
- A "skip to content" link appears first for keyboard users, and focus is clearly outlined.
- Menus, question lists and the diagnosis tool work with a keyboard, and the diagnosis tool announces its progress and result to screen readers.
- Every form field has a visible label, and form messages are announced when they appear.
- Pages use one main heading and a logical heading order.
- Images that carry meaning have text alternatives; decorative graphics are hidden from assistive technology.
- Animation is minimal and is switched off when your device asks for reduced motion.
- Pages reflow on small screens and at 200% zoom without sideways scrolling.
Known limits
Some linked third-party pages, such as Google's documentation, are outside our control. Comparison tables may need horizontal scrolling on very narrow screens. If anything else gets in your way, we want to know.
Tell us about a barrier
Call 1-800-481-8638 or use the contact page. It helps to include the page address, what happened, and the browser or assistive technology you were using. If a form is the barrier, call and we will take the details by phone.
Reviews
We check the site for accessibility whenever pages change and review this statement at least once a year.
