The continuing objective of developers is to make the application compliant with Section 508 and WCAG 2.0 Level A and AA Success Criteria, and as usable as possible for persons using adaptive technology. Most tools follow W3C accessibility guidelines for headings, forms, tables, links, and images, but do not include non-script alternatives to JavaScript, or user messages for pop-ups or completed actions. Tools following most guidelines include:
