aria-placeholder
StringSupplies a short hint describing the expected value of an input, shown before the user types anything. It mirrors the native `placeholder` attribute for custom textbox widgets built from non-input elements. Placeholder text is not a substitute for a real label, which the field still needs.
Value
Any string of text.
Used on
<input><textarea>
Example
aria-placeholder="…"
<div role="textbox" aria-placeholder="you@example.com" contenteditable></div>References
