Web accessibility in 2019


Most website owners appreciate the importance of making their sites accessible to all their visitors, but the information and documentation can be overwhelming and hard to untangle.


What does ‘web accessibility’ actually mean?

‘Web accessibility’ means that ‘websites, tools, and technologies are designed and developed so that people with disabilities can use them’. (w3.org)

The terms ‘accessibility’ and ‘usability’ are often confused. ‘Accessibility’ means ensuring that all users can access your content, whereas ‘usability’ is about how easy your website is to use.

97.8% of homepages recently failed an accessibility survey

In a recent accessiblity survey by WebAIM, 97.8% of the 1,000,000 home pages they surveyed had detectable WCAG 2 failures. Unless you are in a sector where there are strict legal requirements, your website will be doing a surprisingly good  job if it is 100% accessible.

What’s the law regarding web accessibility?

There are accessibility requirements for public sector websites in the UK. The law is less clear for everyone else, but we aim to optimise website accessibility for all our clients.

What does wave do about accessibility?

We follow the WCAG 2.1 guidelines, and aim to meet the AA conformance level wherever possible.

If you have a spare hour or two, you can read the guidelines at https://www.w3.org/TR/WCAG21/

We aim to keep our knowledge of the guidelines fresh, so that we have them in mind throughout a project. We also have tools to help us test and check accessibility. In particular we like pa11y, and Google’s Audits tools.

What will you need to do?

You should keep accessibility in mind whenever you update or modify your site. The way you write and how you organise your content can affect accessibility. For example, are your page titles and navigation links clear? Titles and links that do not accurately describe your content can harm the accessibility (and usability) of your site.
