While accessibility compliance is a difficult target to hit as portal development continues, we would like to see adoption of ongoing processes that will help us continue to maintain a high degree of accessibility. This should not be viewed only as an attempt to be in compliance with the law; better accessibility generally results in a better experience for all. Just as the move towards a mobile-first design philosophy has resulted in better user interfaces, a move towards accessibile-first implementation will improve the portal for our users. Accessibility is usability."
