In this video, learn the basic concepts of accessibility, and how these core accessibility concepts affect your website.
- [Instructor] To get started, we'll need to begin to explore the fundamental concepts of web accessibility. The World Wide Web Consortium, or W3C, has established a body of guidelines for assessing web accessibility called the Web Content Accessibility Guidelines, or WCAG. These guidelines describe a set of detailed criteria you can use to test your website content for accessibility. WCAG 2.1, the latest update to the accessibility standards, is organized around four key principles of accessibility. Web content must follow all of these four principles. It must be perceivable, operable, understandable, and robust. Perceivable content is content that can be perceived equally using more than one sense. Images can be described with text. Videos are provided with audio descriptions and captions. Because plain text can be interpreted using text-to-audio software, written text is the foundation element of perceivable content. A website is operable if every item on the page can be used by any hardware or software device. Any link, button, or input field can be used with a mouse, with a keyboard, using a touchscreen, such as a mobile phone or tablet, or with the more limited input available in a switch system. Understandable content is content and navigation that, plainly, your visitor can understand. This need can involve several distinct parts. Defining the language of the content, expanding abbreviations, and defining unusual words, consistency and predictability in navigation, and the clarity of input fields for labeling and the handling of errors. A website is robust if it works dependably in current and future browsers, and with all assistive technologies. One aspect of this requires that the code used conforms to defined standards. When writing according to standards, any device that is aware of that standard can display the content. All of these principles work together to help you create pages that allow any user a fair chance at success on your website.
