One major difference is that the values of properties (such as aria-labelledby) are often less likely to change throughout the application life-cycle than the values of states (such as aria-checked) which may change frequently due to user interaction. For example, a slider may have rendered values of small, medium, and large. Free source code and tutorials for Software developers and Architects.
