Hey Azzie Fuzzie,

You are correct, e is event. For this challenge, you need to add an if statement inside event listener and filter out INPUT so only the filtered elements get the background color of yellow.

Here's the final code:

let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if(e.target.tagName === 'INPUT'){
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
});

Hope this helps!
