Relevance
Icons visually represent actions or content. For accessibility, they need clear labels or alt text so screen readers can describe them. Knowing how icons work helps you explain to others how to interact with visual-based navigation, especially if they’re new to a platform or rely on text descriptions due to visual impairments.
