Material Detail

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. AChecker identifies 3 types of problems:

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.

This will delete the comment from the database. This operation is not reversible. Are you sure you want to do it?
