Compliance and accessibility guidelines for Web content
The aDesigner can check the target page's compliance with the following four accessibility guidelines for Web content.
- Web Content Accessibility Guidelines 2.0 (WCAG 2.0):
One of the most popular and latest standards used for Web accessibility.
- Section
508 of the Rehabilitation Act §1194.22 (Section 508): A list
of the Section 508 standards that provides criteria specific to Web-based intranet and Internet information and applications.
Section 508 requires that information technologies developed or purchased by the Federal Government be accessible to people with disabilities.
- Japanese Industrial Standard (JIS) X8341-3: Guidelines for information and communications equipment, software, and services for older people and people with disabilities issued by the Japanese Industrial Standards Committee.

Line numbers are presented in the line

If you want aDesigner to evaluate the runtime Document Object Model of
the target page, deselect this check box. (This is useful when checking certain
JavaScript-based pages.)
Working with the problem list
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 aDesigner and must be addressed.
The Essential problems category consists of both compliance problems and advanced problems detected by aDesigner.
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.
