Hello Yaakov,

The directions ask you to select "select all links inside the <nav> element and assign them to the variable navigationLinks:

You will need to use:


"All", because you want to select multiple links not just one.

Then to target the the links inside navigation you need to use descendent selectors to select the <nav> then go down to the <li> then "descend down to the <a> elements which are the links.

If you still can't figure it out let me know and I will give you more clues or the answer if you really want it. šŸ˜‰

Happy coding!

Hi Heidi, thank you for your answer. My mistake was that I wrote:

document.querySelectorAll('nav li')


document.querySelectorAll('nav a')

I don't really know why the ('nav li') version doesn't work while a li element include an a.

Hi Yaakov,

I actually think ('nav li') would work but since the directions specifically asked for the "links" I think they wanted the answer to me ('nav a').

I'm glad you figured it out.
