"In addition to the traditional editorial issues of content accuracy, spelling, grammar, artwork, and formatting, authors need to think about accessibility."
(Adobe Systems, Inc.)
Welcome to the world of accessibility!
On each page of this guide, the first box is labeled "The Basics." The links in this box will serve as an introduction to the topic as well as a checklist of the most important things you can do. A second box will have a link to the publisher of the application if they've provided a page on accessibility. If you would like to learn more or to learn in alternative format, explore the other boxes on the page.
Even if you're new to the concept, you can make a difference. Many of the steps are simple and take no more time than you already spend to create an online document. Awareness is the key.
