What is web accessibility?
A product design practice
Ensures your website can be interacted with by
everyone including those with issues around:
vision, hearing, motor function and cognition
It is the just, fair and inclusive way to share your
website with the world
Some myths
Its all about headings
Its all about contrast but this can be adjusted in the browser
anyway
Its expensive, time-consuming and so subjective
We will get sued if someone with vision, hearing, motor function
or cognition issues cannot use our site in a particular way
We have to be able to prove our site has been tested to a particular
standard or the government will make us take it down
My user base dont have accessibility needs

What if my website is already live?
Its never too late to start!
 Use available tools and services
 Bake them into your pipeline if time allows
 Perform your own testing/audit/evaluation
manually
 Bring in a good generalist company like Scott Logic
who can help advise you on design and testing

Some helpful tools
Lighthouse
If you are using Google Chrome it comes with an accessibility audit tool built in.
Be aware that it does only catch some types of problems. Behaviour and experience must still be
tested manually. It is an easily accessible good start.
Axe
Axe from Deque is a browser plugin that adds functionality to the Dev Tools.
Provides details about the issue, can highlight the problem in the code or on the page, and even
suggests some way to fix it.
Wave
The Web Accessibility Evaluation Tool - another browser plugin.
Audits for a wide range of issues including contrast analysis.
