ariaModal property
      
      String?
      get
      ariaModal
      
    
    
The ariaModal property of the Element interface reflects the value
of the aria-modal attribute, which indicates whether an element is modal
when displayed. Applying the aria-modal property to an element with
role="dialog" replaces the technique of using aria-hidden on the
background for informing assistive technologies that content outside a
dialog is inert.
Implementation
external String? get ariaModal;
      
      set
      ariaModal
      (String? value) 
      
    
    
    
Implementation
external set ariaModal(String? value);
