# JSON Grammar

The JSON grammar describes the elements that you can use in a JSON page object.

Here's a sample outline of a page object.

```json
{
  "elements": [],
  "methods": [],
  "shadow": {
    "elements": []
  },
  "root": true,
  "selector": {
    "css": "one-record-home"
  }
}
```

For more details, start with [Root Elements](https://developer.salesforce.com/docs/platform/utam/references/utam-grammar/root-elements.md).
