SC 4.1.2 - What does "Name, Role, Value" mean?
A screen reader user reaches a control on your page. Three things have to be true for them to use it. They have to know what it is (a button, a checkbox, a tab), what it is called (“Add to basket”), and what state it is in (pressed, expanded, checked). Success criterion 4.1.2 is the rule that guarantees all three: every interactive element exposes a name, a role and, where relevant, a value or state.
