The DOM is a tree with all the elements in the document. All the elements you can see are "attached" to the document. When you create a new element it's not attached to the DOM yet. Where would the browser "render" or show it? So an element that hasn't been attached to the document yet is known as a "detached" element or node.

For a node to be added to the DOM you need to call a method on it that will add it to the DOM? e.g. .append()
