Style child element when hover on parent

Question

How to change the style of child element when there is hover on parent element. I would prefer a CSS solution for this if possible. Is there any solution possible through :hover CSS selectors. Actually I need to change color of options bar inside a panel when there is an hover on the panel.

Looking to support all major browsers.

Yes, you can definitely do this:

.parent:hover .child {
   /* ... */
}

This uses the :hover pseudoclass to restrict to elements matching .parent which are also hovered, and the descendant combinator (space) to select any descendant that matches .child.

Here's a live example:

.parent {
  border: 1px dashed gray;
  padding: 0.5em;
  display: inline-block;
}

.child {
  border: 1px solid brown;
  margin: 1em;
  padding: 0.5em;
  transition: all 0.5s;
}

.parent:hover .child {
  background: #cef;
  transform: scale(1.5) rotate(3deg);
  border: 5px inset brown;
}

<div class="parent">
  parent
  <div class="child">
    child
  </div>
</div>
