# --description--

When you add a lower rank heading element to the page, it's implied that you're starting a new subsection.

After the last `h2` element of the second `section` element, add an `h3` element with the text `Things cats love:`.

# --hints--

The second `section` element appears to be missing or does not have both an opening and closing tag.

```js
assert(
  document.querySelectorAll('main > section')[1] &&
    code.match(/\<\/section>/g).length == 2
);
```

There should be an `h3` element right above the second `section` element's closing tag.

```js
assert(
  document.querySelectorAll('main > section')[1].lastElementChild.nodeName ===
    'H3'
);
```

The `h3` element right above the second `section` element's closing tag should have the text `Things cats love:`. Make sure to include the colon at the end of the text.

```js
assert(
  document
    .querySelectorAll('main > section')[1]
    .lastElementChild.innerText.toLowerCase()
    .replace(/\s+/g, ' ') === 'things cats love:'
);
```

There should be an `h2` element with the text `Cat Lists` above the last `h3` element that is nested in the last `section` element'. You may have accidentally deleted the `h2` element.

```js
const secondSectionLastElemNode = document.querySelectorAll('main > section')[1]
  .lastElementChild;
assert(
  secondSectionLastElemNode.nodeName === 'H3' &&
    secondSectionLastElemNode.previousElementSibling.innerText
      .toLowerCase()
      .replace(/\s+/g, ' ') === 'cat lists'
);
```
