ARIA Hidden
A) ARIA Hidden
Here you can enable the aria-hidden attribute on the module. The aria-hidden attribute can be used to hide the module from assistive technologies. This can be used to improve the experience for assistive technology users by hiding decorative or duplicated content.
B) Hidden Selector
By default, the aria-hidden attribute is applied to the main module element. Here you can enter a selector for a specific element within the main module to apply the attribute instead. You may enter a single id, class or tag only. For example: entering h3 would apply the attribute to .et_pb_module h3, entering #my_id would apply the attribute to .et_pb_module #my_id, and entering .my_class would apply the attribute to .et_pb_module .my_class.
For detailed information on the aria-hidden attribute and its uses, please see the W3C Web Accessibility Initiative (WAI) documentation.
