The footer element is used to define a footer for a document or section. A footer typically contains information about the author of the document, copyright data, links to terms of use, contact information, and more.
After the main element, add a footer element.
You have either deleted the main element or it is missing an opening tag or closing tag.
assert(document.querySelector('main') && code.match(/<\/main>/));
Your footer element should have an opening tag. Opening tags have the following syntax: <elementName>.
assert(document.querySelector('footer'));
Your footer element should have a closing tag. Closing tags have a / just after the < character.
assert(code.match(/<\/footer\>/));
Your footer element should be below the closing main element tag. You have put it somewhere else.
assert(document.querySelector('main').nextElementSibling.nodeName === 'FOOTER');
