01Begin with structure
Headings, landmarks, labels, and buttons give users and assistive technology a reliable map of the page.
Semantic elements provide the first layer of a usable interface. A real button communicates action, a label identifies a field, and headings reveal the shape of a page. These choices help keyboard and assistive technology users while making the code easier to understand and maintain.
02Test the interaction
Keyboard navigation and focus behavior reveal problems that a static design review cannot.
Test with a keyboard through the entire journey, including menus, forms, errors, and dialogs. Focus needs to be visible and move in a logical order. Reduced-motion preferences and contrast should be checked on the actual components and backgrounds used in production, not only in a design file.
03Include real content
Meaningful labels and error messages are part of accessibility, not decoration added afterward.
Clear words are as important as clean markup. An error message should explain what happened and how to fix it. Link text should make sense out of context. Real content reveals truncation, ambiguous instructions, and overloaded layouts that placeholder copy can hide.
