The miChecker can check the target page's compliance with the following four accessibility guidelines for Web content.
To choose the accessibility guidelines to check:
Two categories appear in the Tree View pane, Essential problems and User checks. They are classified according to whether or not they are automatically detected.
Essential problems are automatically detected by miChecker and must be addressed. The Essential problems category consists of both compliance problems and advanced problems detected by miChecker. User checks are problems that should be reviewed individually, and the author must decide whether to resolve them or to postpone resolving them (or to ignore them).
In the Line View pane, each line shows the corresponding checkpoints of the selected accessibility guidelines. The checkpoints of WCAG, Section 508, and JIS are specified in their own formats, with digits divided by a period (e.g. "13.6"), a letter (e.g. "o"), two digits and a letter divided by periods (e.g. "5.1.a"), or a digit (e.g. "8"), respectively. These formats and the corresponding descriptions and techniques you can use to address each problem are described at the websites of these guidelines.
The help pages are available by right-clicking a line and selecting View Help from the context menu. The context menus are also available by pressing Shift+F10.
