The WCAG guidelines were updated from version 2.0 to 2.1 in June 2018. The updates in 2.1 cover changes in technology that have occurred since the previous version, and also address areas that were underrepresented in 2.0. What does this mean for you? Not a lot right now. The compliance level targeted is still WCAG 2.0 Level AA, and the 2.1 success criteria are in addition to those already existing in 2.0.
Webpage designers often have aesthetic preferences and may want everyone to see their webpages in exactly the same color, size and layout. But because of their disability, many people with low vision do not see webpages the same as other people. Some see only small portions of a computer display at one time. Others cannot see text or images that are too small. Still others can only see website content if it appears in specific colors. For these reasons, many people with low vision use specific color and font settings when they access the Internet – settings that are often very different from those most people use. For example, many people with low vision need to use high contrast settings, such as bold white or yellow letters on a black background. Others need just the opposite – bold black text on a white or yellow background. And, many must use softer, more subtle color combinations.

While the impact of the Americans with Disabilities Act on online accessibility is likely to remain vague for the foreseeable future, there is no question that equal access is a major concern for users across America, and for the courts that serve those users. In lieu of a clear set of national guidelines, abiding by WCAG accessibility standards remains the best option for most organizations. It’s not just a smart way to avoid accessibility lawsuits and negative publicity—providing accessible solutions for all users is just the right thing to do.
Courts have essentially taken three positions when approached with this issue. Some courts take the position that the ADA applies to all commercial sites because the law was meant to protect disabled individuals from having a more difficult time than able-bodied individuals from doing business. That is why the website Scribd was unable to get a case summarily dismissed and ended up settling.
