We put our users first in all that we do, and accessibility is no exception. Accessibility is about ensuring that every user, regardless of his or her capabilities , can fully enjoy using Yahoo’s products. That is why we are excited to introduce our newAccessibility page, hosted by the Yahoo Accessibility Team.
The Accessibility team is based in Sunnyvale, performs user studies and works side-by-side with our product teams during development to make sure that our mobile and web products can be used and enjoyed by everyone. Some of the ways our products become more accessible are through the use of high-contrast colors, resizable text, alt-text (descriptions) for images and user interface elements, and support for closed captions and subtitles on videos.
