Slides for a presentation I gave originally to WordCamp London on Saturday 23rd November 2013 and at many subsequent Wordcamps and WordPress meetups. The most recent occasion being WordPress User Group London on October 20th 2015 for which I revamped some of the slides to remove outdated examples.
The WCAG 2 guidelines provide a comprehensive list of best practices for creating accessible websites. But there is a lot of information and the success criteria can be a bit impenetrable in places.
I've distilled down some common accessibility issues into a series of 16 yes/no questions that anyone can ask about their own website. If you can answer these questions correctly, your website will be more accessible than many.
The presentation poses the questions and shows some examples of problems that accessibility testers find, as well as pointing out some of the best practices to achieve good web accessibility.
