## Notes


Used in Roles
No role required.
This property defines element relationships and associations that cannot be readily determined from the document structure. The **aria-controls** property is used primarily by elements where the [**role**](/html/attributes/role) property value is `group`, `region`, or `widget`. Compare this usage with that of the [**aria-owns**](/aria/attributes/aria-owns) property. **Note** For cross-browser compatibility, always use the WAI-ARIA attribute syntax to access and modify ARIA properties, for example `object.setAttribute("aria-valuenow", newValue)`.
