// This is how you would complete this challenge
// Just put this code inside the 'if' statement
e.target.previousElementSibling.className = 'highlight';

e.target  //<--- get's the element tag that's being clicked, in this case we got back the 'button' tag
.previousElementSibling  //<--- select's the previous element from the current that's being clicked,
// in this case when we got back 'p' tag. If you look at the html code below, you can see
// that the previous element from 'button' is 'p'.
// <p>Element Selection</p><button>Highlight</button>
.className  // <--- allows us to change the class of a particular tag element
