Hi Jiho, the tagName property is always an uppercase value. So, in order for your equality check to work correctly, you have to change input to INPUT.

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

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