Web accessibility is a field of research that focuses on making websites and web applications accessible to individuals with disabilities. This includes ensuring that websites are designed and developed in a way that allows people with visual, auditory, motor, and cognitive impairments to navigate and interact with them effectively. Research in web accessibility often involves studying the impact of different design elements, technologies, and user interfaces on accessibility, as well as developing guidelines and tools to help designers and developers create more inclusive web experiences. The goal of web accessibility research is to ensure equal access to information and services online for everyone, regardless of their abilities.
