Accessibility explained
Accessibility aims to make digital products perceivable and usable by more people, including those with visual, hearing, motor, or cognitive differences. Semantic structure, keyboard support, and clear content all matter. Accessibility also addresses temporary injuries and situational limits such as a noisy environment. Perceivable content, operable controls, understandable behavior, and robust implementation need to work together.
Why it matters.
Low-contrast text, mouse-only controls, and unlabeled fields exclude some people. Accessible design considers different ways of using a product. An access barrier can prevent a task entirely, so its effect may be greater than ordinary friction. Design, content, and development choices all need review.
Let's look at an example.
Think of a form.
Visible field labels and clear error explanations help someone using a screen reader understand what to enter and where. An error shown only in red may be missed. A clear message beside the field and sensible focus behavior make the problem easier to find and correct.
How to apply it.
- 01
Try using the page with only a keyboard.
- 02
Check the contrast of text and controls.
- 03
Give meaningful elements the right labels and structure.
