State change detection (state-changes)
User interface components with changing states (e.g. checkboxes) include properties such as aria-checked, aria-selected or aria-expanded.
Missing aria-valuemin / aria-valuemax / aria-valuenow:
This custom slider is missing required ARIA value attributes. Elements with role="slider" must expose aria-valuemin, aria-valuemax, and aria-valuenow.
Assistive technologies cannot determine the slider's current value or range without these attributes.
