About this initiative

The «Accessibility Developer Guide» in its entirety is the result of many years of hands-on practice in the field of testing websites for accessibility, as well as developing accessible web applications. The daily experience of user experts with special needs, blended together with the profound technical knowledge of fullstack web developers, resulted in forming the «Accessibility Alliance».

«Access for all»

On one side of the «Accessibility Alliance», there is the Swiss Foundation «Access for all», which is the initiator and leader of the whole initiative. It consists of a small team of accessibility experts and web developers, half of which having special needs themselves.

The foundation is in business since the year 2000, and since then has accompanied hundreds of local and international websites in the process of becoming accessible. The basis for this have always been the official guidelines like the Web Content Accessibility Guidelines (WCAG) and Accessible Rich Internet Applications (ARIA), combined with the real-life experiences of those employees with special needs, and profound expertise of fullstack web developers. In one sentence: the contents of this guide are the result of nearly two decades of hands-on experience in all topics accessibility.

With the Accessibility Developer Guide, the «Access for all» foundation provides developers with an instrument that offers practical and concrete support in the implementation of accessible web offerings. As an open source project, the Accessibility Developer Guide focuses on sharing and passing on knowledge. All agencies, every woman and every man are invited to join the Accessibility Alliance. Join in a few developer days a year - and you'll be there.

On the other side of the «Accessibility Alliance», there are several acclaimed web agencies. They provided the technical solution and visual design for the guide, gave support in marketing it, etc.

Hinderling Volkart

Until now, web developers have lacked a good, practical reference on accessibility. It doesn't need more rules, but more guidance to make the web usable for everyone. The Accessibility Developer Guide will provide access where hardly anyone has been before, with practical examples, tested by experts and supported by developers. From the very beginning we were convinced of the purpose of this commitment and are proud to be able to contribute a small part to it.

Severin Klaus, Frontend Leader, Hinderling Volkart.


Accessibility is a complex issue and so equally large effort is required to develop the necessary know-how. That is why we have participated in the establishment of the Accessibility Developer Guide, which will be a key tool in the process of creating accessible websites for everyone in the future. We are looking forward to collaborating with the frontend community so that the development of the Accessibility Developer Guide will be continued.

Thomas Jaggi, Expert Frontend Engineer, UNIC AG.


Tim Berners-Lee, the inventor of the World Wide Web once said “The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.”. This aspect which can only be fulfilled by the web is ignored by a wide range of people. We feel responsible for what we develop and for who we develop for. With the Accessibility Developer Guide we finally have a practical guide to accessible web development and can contribute our knowledge.
