Everyone deserves equal access to the web. Approximately 15% of people have some form of impairment (according to the World Health Organisation) - and most people will develop some form of impairment as we age. This session will discuss current and future WCAG (Web Content Accessibility) Guidelines, and demonstrate some common coding errors that software engineers make - and how to correct them. We'll highlight the importance of cultural change - treating accessibility as a foundation stone of all projects, not a feature to be bolted on later. Finally, we'll signpost some excellent resources to help attendees expand their knowledge of accessibility on the web.
