When an element is hovered in HTML, how does it affect other elements?

To affect one element when hovering other elements, an element should be inside another element, i.e. a parent-child element or a sibling element. When placing the mouse cursor over one element, the properties of the other element should change, i.e. the hover effect should be visible.

         height: 150px;
         background-color: orange;
      }
      .child {
         margin-left: 39px;
         width: 100px;
         height: 40px;
         background-color: blue;
         color: white;
      }
      div {
         border: 3px solid red;
      }
      .parent:hover .child {
         background-color: green;
      }
