You got a bit off track, here's a few hints:

  • don't make any changes to the HTML code, it's just there for your reference
  • a better way to select elements would be by using tag names
  • to "select all <a> elements inside the <nav> element" you will need a descendant selector
  • a descendant selector has selectors for the container and the target separated by a space
