Hi Mustafa!

For these use querySelectorAll with a descendant selector.

Keep in mind, a descendant selector is the parent target and children targets separated by a space.

More info:

https://www.w3schools.com/css/css_combinators.asp

This passes task 1:

let navigationLinks = document.querySelectorAll('nav a');

See if you can figure out the other two.

Also, keep in mind that with querySelector and querySelectorAll for ids you need a # and classes you need a .

I hope that helps.

Stay safe and happy coding!
