Developer Component Checklist
A practical checklist for checking custom buttons, links, names, roles, states, keyboard behavior, focus, and ARIA before component issues become review rework.
ARIA Is Not Duct Tape
Use ARIA to describe real component behavior, not to patch over missing HTML, keyboard support, labels, focus, or state.
Button vs Link
Use buttons for actions and links for navigation so people can predict what will happen before they activate a control.
Name, Role, and Value
Check whether custom controls expose what they are called, what they are, and what state they are in before ARIA becomes guesswork.
Color Contrast
Check whether text, icons, controls, and meaningful visual boundaries are easy to see before contrast becomes a late review finding.
Color-Only Meaning
Do not make color carry the whole message. Pair color with text, shape, labels, icons, or patterns so the meaning is available to everyone.
