label-title-only
Form controls should not use title as their only label
Checks that a form control with a title attribute also has a real label (label element, aria-label, or aria-labelledby).
Applies to. Applies to labelable form controls (input, excluding hidden/submit/reset/button/image; select; textarea) that have a non-empty title attribute.
Expectation. The control also has a real label (a wrapping/associated <label>, aria-label, or aria-labelledby), rather than depending on the title attribute alone. A title-only tooltip is not reliably exposed by all assistive technology and is not visible at all until hover/focus, unlike a persistent visible label.
Examples
<input title="Name">
The `title` attribute is the field's only naming mechanism — it shows as a tooltip, not a persistent visible label.
<label>Name <input title="Enter your full name"></label>
A real `<label>` already names the field; `title` is just supplementary.
