Before adding any new content, you should make use of a section element to separate the cat photos content from the future content.

The section element is used to define sections in a document, such as chapters, headers, footers, or any other sections of the document. It is a semantic element that helps with SEO and accessibility.

html

<section>
  <h2>Section Title</h2>
  <p>Section content...</p>
</section>

Take your h2, p, and anchor (a) elements and nest them in a section element.

--hints--

Your section element should have an opening tag. Opening tags have the following syntax: <elementName>.

assert(document.querySelector('section'));

Your section element should have a closing tag. Closing tags have a / just after the < character.

assert(code.match(/<\/section\s*>/i));

The entire section element should be between the opening and closing tags of the main element.

assert(document.querySelector('section').parentNode.nodeName === 'MAIN');

The existing h2, two p elements, and anchor (a) element should be between the opening and closing tags of the section element.

const childrenOfSection = [...document.querySelector('section').childNodes];
const foundElements = childrenOfSection.filter((child) => {
  return ['H2', 'A', 'P'].includes(child.nodeName);
});
assert.lengthOf(foundElements, 4);

The h1 element should not be nested in the section element.

const childrenOfSection = [...document.querySelector('section').childNodes];
const includesH1 = childrenOfSection.some((child) => child.nodeName === 'H1');
assert.isFalse(includesH1);
