About AChecker
AChecker is used to evaluate HTML content for accessibility problems by entering the location of a web page, uploading an html file, or by pasting the complete HTML source code from a Web page. AChecker produces a report of all accessibility problems for your selected guidelines. Known problems: These are problems that have been identified with certainty as accessibility barriers. You must modify your page to fix these problems; Likely problems:These are problems that have been identified as probable barriers, but require a human to make a decision. You will likely need to modify your page to fix these problems; Potential problems: These are problems that AChecker cannot identify, that require a human decision. You may have to modify your page for these problems, but in many cases you will just need to confirm that the problem described is not present.
