Concentrating on WCAG alone can feel like accessibility is always binary. When thinking about all the success criteria of the WCAG we can quickly conclude that there is not a single medium sized website in the world that conforms totally. A reflection on perfectionism, conformance and reality.
Sustainability and accessibility are absolutely interconnected. Recent sustainability guidelines, although still in draft version, are quite often referring to accessibility, so I wanted to expose parts where accessibility is beneficial to sustainability.
Sometimes best practices are passed as WCAG requirements and that can make accessibility more difficult for some people to implement. We need to understand what WCAG actually requires and what it does not before we try to impact other people.
