Hi Alexandru!

You have to select all links (anchor items) with your querySelector, so use querySelectorAll. QuerySelector is basically a javascript equivalent of CSS selector, so you can use the same syntax you are used to with CSS.

If you need help with CSS selectors you can check out this course: https://teamtreehouse.com/library/intro-to-selectors And if you want to learn more about querySelector i suggest you check out this page: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector

Also you don't have to call any methods (.length) on the selected items, if you were trying to return all the anchor tags instead of the first, just use document.querySelectorAll instead.

Hope i could be of help to you, if you are still stuck or have any other questions feel free to ask!
