# ShadowHost

`ShadowHost` is a small renderless mainly utility component for easily attaching
ShadowDOM to any applicable DOM node. It mainly exists to provide a context for
passing around a reference to the element to be used for the shadow template,
but named appropriately for recognition.

If you are looking to write a custom element, please use the `CustomElement`
component. If you are simply attaching ShadowDOM to a native HTML element then
this is the component for you.

```hbs preview-template
<ShadowHost as |shadow|>
  <div
    {{did-insert shadow.host}}
  >
    <shadow.Template>
      <p>hi</p>
    </shadow.Template>
  </div>
</ShadowHost>
```
