Level AAA guidelines

Level AAA represents the highest level of conformance and accessibility. Contrary to popular belief, level AAA is not always hard or impossible to meet. There are many technical reasons why items will be designated as AAA, but what I have experienced over time is a lot of these are just included as part of good design and usability.

Not all guidelines are applicable to every site. That doesn't mean you can't meet AAA. Some guidelines are AAA because they require extra effort and resources that may be difficult or excessive for most sites. If your content is vital, or maybe something someone paid for, then you should consider extending the effort. The purpose of all the guidelines are to increase usability for everyone. So if that is important to you and you have the resources, go for. Keep the people consuming your content in mind and use your best human-focused judgement. You could level up from removing barriers to potentially reducing friction.

To be clear, accessibility is not a checklist or a tool, and doing everything exacly as documented here will not always guarantee an accessible, or compliant site. It's important to note that how you deliver accessibility is unique and completely dependant on your particular site content, and users.
