WAI Web Accessibility Tutorials

Guidance on how to create websites that meet WCAG: This collection of tutorials shows you how to develop web content that is accessible to people with disabilities, and that provides a better user experience for everyone.

Accessibility Developer Guide ADG

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 full stack web developers, resulted in forming the «Accessibility Alliance».

h123 Bookmarklet (Heading structure)

The bookmarklet h123 from Hinderling Volkart creates a quick overview of the heading structure of a website.

Use this bookmarklet to get an impression of how screen reader users can get som orientation on your site and how they can navigate within it.

Web Developer browser extension by Chris Pederick

The Web Developer Extension extends your browser with various Web Developer Tools. The extension is available for Chrome, Firefox and Opera and runs on every platform.

We particularly recommend the function for visually displaying the alt attributes for images in the browser. This allows for an efficient assessment of the usefulness of existing alternative texts.

Colour Contrast Analyser (CCA) by Steve Faulkner

CCA is a perfect tool for checking the contrast ratio between font and background.

The Colourpicker function allows a first assessment. However, in case of ambiguity we recommend to enter the HEX value directly into the corresponding fields.

Windows High Contrast Mode (Win HCM)

The mode for high-contrast display of screen contents, which can be activated by default in Windows operating systems, allows an easy and quick check of the adaptability of websites to individual color schemes.

Win HCM can be easily turned on and off using the key combination [Alt] + [Shift] + [PrtScr].

Screenreader as test tools

Anyone who seriously wants to test for accessibility cannot avoid the use of screen readers. The compatibility of websites for the use of screen readers must be considered THE litmus test for accessibility.

We especially recommend NVDA as screen reader of choice for testing purposes.

Web Content Accessibility Guidelines (WCAG) 2.1

WCAG 2.1 extends Web Content Accessibility Guidelines 2.0 [WCAG20], which was published as a W3C Recommendation December 2008. Content that conforms to WCAG 2.1 also conforms to WCAG 2.0.

Web Content Accessibility Guidelines (WCAG) 2.0

Web Content Accessibility Guidelines (WCAG) 2.0 covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these. Following these guidelines will also often make your Web content more usable to users in general.

WCAG 2.0 success criteria are written as testable statements that are not technology-specific. Guidance about satisfying the success criteria in specific technologies, as well as general information about interpreting the success criteria, is provided in separate documents. See Web Content Accessibility Guidelines (WCAG) Overview for an introduction and links to WCAG technical and educational material.

WAI-ARIA Overview

WAI-ARIA, the Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies. Currently certain functionality used in Web sites is not available to some users with disabilities, especially people who rely on screen readers and people who cannot use a mouse. WAI-ARIA addresses these accessibility challenges, for example, by defining new ways for functionality to be provided to assistive technology. With WAI-ARIA, developers can make advanced Web applications accessible and usable to people with disabilities.

DiagramCenter.org - Image Description

Image description is often the easiest and fastest way to provide information about an image to a reader who cannot access it visually. Below are resources developed by the DIAGRAM Center to help content creators provide image descriptions. For information on technical standards related to attaching descriptions to images in digital content, see the Born Accessible Publishing page.

Publishing@W3C - EPUB3

The web was created to provide access to a “universe of documents.” Since then, the Web has become many things, but documents and, by extension, publications, have remained close to the heart of the Web.

Many publishers use EPUB to bring digital content to their readers. EPUB is built from Web technologies, but publishing uses the web for so much more, from everyday matters of communication and marketing to learning management systems and online journals. Print and digital books are bought and sold on websites.

WordToEPUB

Using Microsoft Word and WordToEPUB, you can convert documents to the latest EPUB 3 format. EPUB is a wonderful format for reading publications on laptops, tablets, and smartphones, and it includes features such as rich navigation and great accessibility. The EPUB files created with this tool can be used in a wide variety of reading apps on any platform, with the ability to personalize visual features such as colors, font, text size, and layout. Many reading apps have other useful features such as read aloud, the ability to add comments and bookmarks and support for electronic braille.
