## Description
Before adding any new content, you should make use of a `section` element to separate the cat photos content from the future content.
Take all the elements currently located within the `main` element and nest them in a `section` element.
## Tests
```yml
tests:
- text: "Your `section` element should have an opening tag. Opening tags have the following syntax: ``."
testString: assert( document.querySelector('section') );
- text: Your `section` element should have a closing tag. Closing tags have a `/` just after the `<` character.
testString: assert( code.match(/<\/section\>/) );
- text: The entire `section` element should be between the opening and closing tags of the `main` element.
testString: assert( document.querySelector('section').parentNode.nodeName === "MAIN" );
- text: The existing `h2`, comment, `p` element, and anchor (`a`) element should be between the opening and closing tags of the `section` element.
testString: |
const childrenOfSection = [ ...document.querySelector('section').childNodes ];
const foundElems = childrenOfSection.filter(child => {
return ['H2', 'A', 'P'].includes(child.nodeName);
});
assert( foundElems.length === 3 );
```
