Perceivable
In web accessibility, Perceivable means that information and user interface components must be presented to users in ways they can sense whether through sight, hearing, or touch—ensuring that content is accessible to individuals with sensory disabilities.
Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language.
