The event target should never be an empty string, it should be a reference to the element that was clicked.

What you may want to do there is check what kind of element is is, by comparing the "tagName" property to an upper-case version of the desired tag's name.

Many thanks Steve, I tried the if statement again with 'input' as uppercase and it worked this time

let section = document.getElementsByTagName('section')[0]; section.addEventListener('click', (e) => { if('INPUT') { = 'rgb(255, 255, 0)'; } });
