We start every web site ADA testing project by performing automated tests using industry standard commercial software. This generates a preliminary report specific to WCAG 2.1 / Section 508 compliance level required - A, AA or AAA - which serves as a basis for in depth code review and manual testing with assistive technologies, such as screen readers. Once a full list of issues has been identified with both automated and manual testing, we go through each issues to verify its severity and occurrence.

Frameworks such as WordPress and Drupal are great in giving us ready to use, configurable website plugins and modules. The drawback is that sometimes these plugins lag behind in terms of compliance, which requires manual changes to code. In this example we will look at bringing Revolution Slider into compliance with Americans with Disabilities Act (ADA) requirements for website, specifically for ADA compliance with screen readers.
Americans with Disabilities Act (ADA) is slated to become a legal requirement for websites selling goods or services directly to the public starting in 2018. There are already plenty of good resources for identifying code-based compliance, but image compliance is a trickier matter. As a quick solution, we put together a Color Check tool that in two clicks allows you to select foreground and background colors and performs contrast validation on selected colors in accordance with ADA requirements.
