It has warned 'Bummer! Was expecting 3 links not 0' even I set class for each 'li' of nav. What's wrong ?

Hi there! First, you are not meant to alter the HTML in any way. Secondly, the class you added is invalid as you have extraneous spaces in the code. It should be class="some-class" without spaces around the equals sign. But, as stated, you should not be adding classes to anything. Finally, even if that had been valid it would not have selected the links, it would have selected the list items. The challenge is asking you to select the links which are represented by the anchor or <a> tag.

I feel like you can get it with these hints, but let me know if you're still stuck! :sparkles:

I did it with " document.querySelectorAll('nav a'); " . Is this what this challenge want?
