While the ADA regulations don't mention websites, the U.S. Department of Justice frequently cites recommendations such as the Web Content Accessibility Guidelines (WCAG) 2.0 and 2.1 created by the World Wide Web Consortium (W3C), an international group that helps create and promote web standards. The WCAG highlight different criteria for making websites more accessible to people with disabilities, such as including captions for audio content and using high-contrast color schemes.
Enough Time: Users have sufficient time to read and use the website’s content. If part of the website has a time limit, users are able to turn off the time limit, or they can adjust or extend it to at least ten times the default limit (unless the time limit is essential to the website’s functionality, such as auction websites like eBay). Content that moves, blinks, or automatically updates can be paused or stopped unless it’s essential to the website’s functionality.

The event, known as the "Capitol Crawl", was an image that legislators couldn't ignore, Bauer said. She had fought since the 1960s to legally protect the rights of people with disabilities, and with that heroic display, she said, lawmakers simply couldn't go back to their constituents without action.
