I asked Chat GPT: “what is accessibility?”
Chat GPT responded: “Accessibility refers to the design of products, devices, services, or environments that are usable by people with various disabilities. It ensures that everyone, regardless of their physical or cognitive abilities, can access information and participate fully in society. This includes considerations for visual, auditory, motor, and cognitive impairments.
In digital contexts, accessibility often involves creating websites and applications that can be navigated and understood by screen readers, providing text alternatives for images, ensuring keyboard navigation, and using clear and simple language. In physical spaces, it can involve features like ramps, elevators, and proper signage. The goal of accessibility is to create an inclusive environment for all.”
An example of something that would be unaccesable is something like a bright yellow text on a white background, this will be inaccesable for the visualy impared.
An example of text that would work is a navy text on a faded paper yellow background, it contrasts enough so people can read it.
