Links and form controls are the fundamental interactive elements of the web and it is important to understand what makes them accessible and usable to people with disabilities. Participants will learn how the accessible name for a link is computed and how to use W3C Accessible Rich Internet Application (ARIA) techniques to provide programmatic context to improve the meaning of a link to meet WCAG 2.0 requirements. Participants will learn how to label form controls with standard label elements and with ARIA techniques, and how the different techniques affect user interaction. The course will demonstrate the history of techniques for providing accessible error feedback, and the latest techniques available using ARIA. The course will include techniques to provide a consistent visual keyboard focus indicator across browsers for links and form controls. Participants will understand the Section 508 and W3C WCAG 2.0 requirements that apply to links and form controls.
