Web & Digital Accessibility

What is web accessibility?

Web accessibility ensures that online information is accessible to everyone and provides equal access to all users, including those with disabilities. This includes visual, auditory, physical, speech, cognitive and neurological disabilities. Making our web content accessible to people with disabilities also benefits others, including those with changing abilities because of aging or those in temporary situations that impede their ease of accessing web content. Providing accessible website design removes barriers to information essential to our faculty, staff, students, and the community.

What is digital accessibility?

Digital accessibility is the process of making electronic resources accessible to everyone, including people with disabilities. Digital accessibility encompasses web content but also includes non-web products such as hardware, software, assistive technology, and mobile apps. The Worldwide Web Consortium (W3C), an international working group, put together guidelines with the goal of making digital content accessible to everyone, regardless of ability or disability. Washington University strongly encourages that our digital content, including video, audio, documents, and multimedia meets the WCAG 2.0 AA standard when it will be used by students, employees, or the community.


Learn how to build & design accessible content

When you are creating content or editing your website, there are a number of things that content creators can do to ensure your sites provide equal access and equal opportunity to people with diverse abilities.

Accessible Links

Link text is used to describe the destination or purpose of the link. Good link text will help all users navigate your page and assist them in finding what information they need.

Images with Text

Images with text can negatively affect both your website and the user's experience in many ways. Not only do they cause problems for people with vision impairments, but also for people who are just trying to find information on your website.

Plain Language, Purpose, & Readability

Plain language is not only essential for people with disabilities but also for users who are encountering an unknown topic or language. Using plain language will help all of your users find what they need, understand what they find, and use what they find to meet their needs

Writing Alt Text

Adding an image or a graphic to your content without using alt text or empty alt attribute, can be extremely frustrating for people with visual impairments navigating your site through assistive technologies. Alt text is also helpful for people who have a slow internet connection or limited bandwidth. They are able to use the alt text instead of loading all of the website images.

Headings & Structure

Individuals who are blind or visually impaired often choose to browse a webpage by headings. Individuals who can only use the keyboard for navigation can browse a webpage much faster if the page contains proper headings.
