# Host node

The hostNode option is needed for LiSA Library to inject its markup into your content page. It accepts a CSS selector, addressing an HTML element within your content page.

If you are using the LiSA Library as a standalone embedded player only (option player.host required), hostNode can be omitted.

```
window.LiSA.library.configs.push({
  hostNode: '#your host.node .query-selector',
});
```
