Validation + Presentation
HTML5 validation attributes work with CSS pseudo-classes for feedback; custom widgets need accessible roles and keyboard support.
:user-invalid
Some browsers expose :user-invalid to style fields after interaction—reduces aggressive error styling on load.
Custom checkbox pattern
Hide input visually but keep it focusable; style label::before for the box—pair with focus-visible.
