Success Criterion 4.1.2 - Name, Role, Value - Level A
Ensure a correct name, role and value is set for all interactive elements.
The name helps users to identify elements. The screen reader speaks the name and voice control uses the name for actions.
The role lets users know what to expect. The role "button" indicates which action takes place upon activation.
The value informs the user. This includes the state (disabled), properties (selected) and values (50%).
For example, give a tab the name "Home", the role "tab", the property "selected" and the value "1 of 4".
