Web Content Accessibility Guidelines 2.0

From UX Collective: https://uxdesign.cc/web-content-accessibility-guidelines-2-0-d5fa4171acad

An estimated 48.9 million people in the United States have a disability. Many of us without disabilities take for granted the usability of the Internet, apps, and websites because we have never experienced or thought about what it might be like with some sort of disability.

Back in 1999 a document emerged out of the World Wide Web Consortium (W3C) called the Web Content Accessibility Guidelines (WCAG). It covered a wide range of recommendations for making Web content more accessible.

The intent of the document is to provide guidelines for making content accessible to a wider range of people with disabilities, including blindness, low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity, and combinations of these.

Since 1999, the guidelines have evolved. Version 2.0 is the latest iteration, and for UX Designers who are influencing and shaping better human experiences with products and technology, it’s a must-read if not a vital part of the UX toolbox.

Here’s a summary of the guidelines’ four main parts. Links are included which will take you directly to that part of the WCAG guideline.


Information and user interface components must be presentable to users in ways they can perceive.

Provide text alternatives to any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language.

Provide alternatives for time-based media.

Create content that can be presented in different ways without losing information or structure.

Make it easier for users to see and hear content including separating foreground from background.


User interface components and navigation must be operable.

Make all functionality available from a keyboard.

Provide users enough time to read and use content.

Do not design content in a way that is known to cause seizures.

Provide ways to help users navigate, find content, and determine where they are.


Information and the operation of a user interface must be understandable.

Make text content readable and understandable.

Make Web pages appear and operate in predictable ways.

Help users avoid and correct mistakes.


Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.

Maximize compatibility with current and future user agents, including assistive technologies.

Ironically, the 10 UX Design heuristics share some commonalities with these guidelines. It’s good to see that this is getting more attention because from a user experience point of view, we need to show empathy for those 48 million people that experience the Web in a drastically different way.

Have any stories to share about designing for people with disabilities? Always great to hear. Thanks for reading.
