Distinguishable: To assist color-blind users and those with other visual impairments, color is never used as the sole means of conveying information or prompting the user. Audio lasting more than 3 seconds can be paused, or the volume can be controlled independently of the system volume. Regular text has a contrast ratio of at least 4.5:1, and large text has a contrast ratio of at least 3:1. In addition, text can be resized up to 200 percent without causing issues with the website.
Because the ADA establishes overlapping responsibilities in both EEOC and DOJ for employment by State and local governments, the Federal enforcement effort is coordinated by EEOC and DOJ to avoid duplication in investigative and enforcement activities. In addition, since some private and governmental employers are already covered by nondiscrimination and affirmative action requirements under the Rehabilitation Act of 1973, EEOC, DOJ, and the Department of Labor similarly coordinate the enforcement effort under the ADA and the Rehabilitation Act.
Your site would need to have a text only option, with all functionality accessible through a keyboard for visitors with mobility issues. Once you make these and other changes to meet ADA guidelines, your site would need to be tested by a website development company familiar with ADA compliance issues to be sure that visitors who use assistive technology such as screen readers are able to access your web content fully.
In some circumstances, longer and more detailed text will be necessary to convey the same meaningful information that other visitors to the website can see. For example, a map showing the locations of neighborhood branches of a city library needs a tag with much more information in text format. In that instance, where the map conveys the locations of several facilities, add a “longdesc” tag that includes a text equivalent description of each location shown on the map – e.g., “City Center Library, 433 N. Main Street, located on North Main Street between 4th Avenue and 5th Avenue.”
It isn’t a problem by default, a lot of it comes down to how it is built. I’d suggest either considering a highly accessible contingency option, or build those components in such a way that there is a level of accessibility baked into it.
