Accessibility and usability are two critical aspects of design and development that focus on different elements of user experience. Accessibility ensures inclusivity, ensuring websites and web applications are accessible to all, including people with visual, auditory, motor, and cognitive impairments. On the other hand, usability refers to ease of use, allowing users to easily navigate through the website or web application and meet the user's needs efficiently and effectively. While accessibility addresses people with disabilities or limitations, usability aims to address the needs of all users who use a website.
