Our goal
We aim to make core informational content usable across common desktop and mobile browsers and compatible with standard browser accessibility features.
Using the site
You can use browser zoom, text resizing, keyboard navigation, reader modes, and operating-system accessibility settings. Third-party maps or embedded forms may have their own accessibility behavior.
Third-party content
Some features are supplied by third parties and may not be fully controlled by this website. If an embedded feature is difficult to use, consider opening the provider's service directly or using browser assistive technology.
Ongoing improvement
Accessibility is an ongoing process. When pages are redesigned or new tools are added, readability, keyboard access, labeling, and mobile usability should be considered as part of quality assurance.
