you are close. getElementsByTagName() is a method, you are calling it on document and storing the return in a constant called body. you call the method with the argument of the element you want, so body, as a string ('body').

Here is what the code should look like.

const body = document.getElementsByTagName('body');

Here is also a link to show you CSS selectors for future reference when you get stuck. https://www.w3schools.com/cssref/css_selectors.asp

The CSS selectors really only pertain to querySelector seeing how getElementsByTagName is strictly for the HTML element tag name. Sorry for the confusion if any.
