The querySelector and querySelectorAll methods use CSS selectors to define which elements to select. They work in the same way except the querySelector method only returns the first element that matches the selector passed as an argument, while querySelectorAll returns a nodelist of all the elements that match the selector passed as an argument. Furthermore, the querySelectorAll method returns a nodelist EVEN if only one element matches the selector. You can read up a bit on nodelist at develop.mozilla.org.
Here’s a link to an mdn article on document.querySelectorAll: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll
If you don’t have any experience with CSS just yet, I would suggest googling “css selector for a class” to figure out how to write the selector you’ll pass into document.querySelectorAll.
Hope this helps. If not, let me know.
