The APG assumes basic understanding of web development, especially of HTML and CSS.

The practices section gives in-depth explanation of how to satisfy a variety of accessibility needs that surface when making rich internet application experiences accessible.įor instance, the practices section on providing accessible names and descriptions gives detailed descriptions of seven different naming techniques as well as a table providing guidance for naming more than 80 types of elements. The APG is organized into two major sections: patterns and practices.Įach pattern explains how to make a common user interface element, such as a button, menu, or dialog, accessible, and provides functional example implementations of the pattern. It also explains essential practices related to these patterns, such as how to convey web page structure with ARIA landmark regions and effectively utilize the many ways of encoding accessible names. The APG describes how to convey accessibility semantics and implement keyboard accessibility for many common design patterns, ranging from typical buttons and popup menus to complex tree grids. In addition, keyboard accessibility requires the button to be focusable, and keyboard conventions call for pressing Enter or Space to activate the button when it is focused. To make that icon accessible to a screen reader user, one of the semantics that needs to be communicated is that the element represents an interactive button. It also provides guidance on some closely related topics, such as supporting operating system settings for high contrast and reduced motion.Īccessibility semantics refer to the meaning of user interface elements that need to be conveyed to assistive technology users in order for those users to understand and use the elements.įor example, people who can visually perceive a search icon button understand the element can be activated to perform a search by the way it is styled and positioned. The ARIA Authoring Practices Guide (APG) explains how to create accessible web experiences for users of assistive technologies and keyboard interfaces by developing web sites that properly convey accessibility semantics and implement common keyboard conventions.
