# --description--

The `thead` and `tbody` elements are used to indicate which portion of your table is the header, and which portion contains the primary data or content.

Add a `thead` and `tbody` to your first `table`, below the `caption` element.

# --hints--

Your first `table` element should have a `thead` element.

```js
assert(document.querySelectorAll('table')?.[0]?.querySelector('thead'));
```

Your first `table` element should have a `tbody` element.

```js
assert(document.querySelectorAll('table')?.[0]?.querySelector('tbody'));
```

Your `thead` element should be immediately below your `caption` element.

```js
assert(document.querySelector('caption')?.nextElementSibling?.localName === 'thead');
```

Your `tbody` element should be immediately below your `thead` element.

```js
assert(document.querySelector('thead')?.nextElementSibling?.localName === 'tbody');
```
