For someone who cannot complete a form by keyboard, cannot read text because of contrast, or cannot understand what is on screen with assistive technology, a good-looking interface simply does not work.
Three areas to look at first
- Perceivable: are text, colour, media and icons understandable for different needs?
- Operable: can the whole flow be used by keyboard and touch device?
- Understandable: does an error message say what happened and how to fix it?
The technical side of visual design
Good contrast is not only colour choice. Visible focus states, resizable text, buttons with sufficient tap area, and the ability to reduce motion are the accessibility side of design.
Why semantic HTML matters
A div can look like a button visually, but keyboards, screen readers and browsers cannot know what it is on their own. Correct HTML elements and meaningful aria labels let the interface reach people through different channels.
How testing progresses at WYN
Automated checks are a good start; human testing, keyboard navigation, different zoom levels and mobile use show real quality. We check accessibility while components are designed, not at the end of the project.
