Interactive form controls must have Labels/Tooltips associated

Effective form labels are required to make forms accessible. The purpose of form elements such as checkboxes, radio buttons, input fields, etc., is often apparent to sighted users, even if the form element is not programmatically labeled. Screen reader users require useful form labels to identify form fields. Adding a label to all form elements eliminates ambiguity and contributes to a more accessible product.

When labels for form elements are absent, screen reader users do not know the input data expectations. Screen readers cannot programmatically determine information about input objects without an established label relationship (or redundant text serving as a label).
