The Accessibility Guidelines Working Group (AG WG) has published a First Public Working Draft of Web Content Accessibility Guidelines (WCAG) 2.2. WCAG provides recommendations for making web content more accessible to people with disabilities. It addresses accessibility of web content on desktops, laptops, tablets, and mobile devices. Following these guidelines also makes your web content more usable to all users in a variety of situations.
¿Qué ha ocurrido? La Iniciativa de Accesibilidad Web, del W3C ya está trabajando en una nueva versión de las Pautas de Accesibilidad Web, la 2.2. Puedes encontrar el actual borrador de trabajo en Web Content Accessibility Guidelines (WCAG) 2.2. First draft y la actualización más reciente de la versión en Web Content Accessibility Guidelines (WCAG) 2.2. Last version.
WCAG 2.2 was initiated with the goal to continue the work of WCAG 2.1: Improving accessibility guidance for three major groups: users with cognitive or learning disabilities, users with low vision, and users with disabilities on mobile devices. Many ways to meet these needs were proposed and evaluated, and a set of these were refined by the Working Group. Structural requirements inherited from WCAG 2.0, clarity and impact of proposals, and timeline led to the final set of success criteria included in this version. The Working Group considers that WCAG 2.2 incrementally advances web content accessibility guidance for all these areas, but underscores that not all user needs are met by these guidelines.
