Web/Mobile App Accessibility is to make sure that the contents of websites and mobile applications are available for all, including not only persons with disabilities but also persons with specific difficulties such as the elderly and persons beset with colour-blindness, cognitive and physical issues such as dyslexia, epilepsy, etc. An accessible website or mobile application not only helps deliver messages wider across, but also improves the general usability for all users. It also helps building a caring and inclusive society. Over the years, the Government has been actively promoting web/mobile app accessibility to facilitate persons with disabilities to access online information and services and enhance their user experience.
