Accessibility check2 to fix

  • Built on a native <input> element, so keyboard focus and screen reader semantics work without extra attributes.
  • No focus style is defined. Add one before shipping, or keyboard users lose track of position.
  • Animates without a prefers-reduced-motion guard. Wrap the animation in that query if motion sensitivity matters to your audience.
