# --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'
);
```
