display: none to block;

parentNode

The read-only parentNode property of the Node interface returns the parent of the specified node in the DOM tree.

Document and DocumentFragment nodes can never have a parent, so parentNode will always return null. It also returns null if the node has just been created and is not yet attached to the tree.

 

if (node.parentNode) {
  // remove a node from the tree, unless
  // it's not in the tree already
  node.parentNode.removeChild(node);
}
