# Finding Shadow DOM elements

Shows how to find elements inside the Shadow DOM.

You can find nodes in a Polymer element's Shadow DOM that are tagged with an
`id` attribute using `this.$.<id>` syntax:

    findNodes: function() {
      this.$.myDiv ... ;
    }

The Polymer documentation refers to this as **automatic node finding**.

Once you've located a Shadow DOM node, you can query for child nodes:

    findNodes: function() {
      this.$.myDiv.querySelector('p') ... ;
    }

Read the
[official documentation for automatic node binding](http://www.polymer-project.org/docs/polymer/polymer.html#automatic-node-finding).
