PF Web Design’s Approch to ADA (Accessible Websites)

Modified on: Thu, 3 Sep, 2018 at 12:22 AM


Web accessibility is the practice of removing barriers that prevent interaction with, or access to websites, for all people. When sites are correctly designed, developed and edited, all users have equal access to information and functionality.

At PF Web Design we have over 20 years of software testing experience. That experience is now helping companies like yours that need to be W3C Compliant reach your goals.

Understanding Conformance

All WCAG 2.0 Success Criteria are written as testable criteria for objectively determining if content satisfies them. Testing the Success Criteria would involve a combination of automated testing and human evaluation. The content should be tested by those who understand how people with different types of disabilities use the Web.

Testing and testable in the context refer to functional testing, that is verifying that the content functions as expected, or in this case, that it satisfies the Success Criteria. Although content may satisfy all Success Criteria, the content may not always be usable by people with a wide variety of disabilities.

Below is a very brief guide to the new changes to
