220 PointsYou have to select the Input-Elements.
let section = document.getElementsByTagName('section')[0];
section.addEventListener('click', (e) => {
if ( e.target.tagName == 'INPUT') {
e.target.style.backgroundColor = 'rgb(255, 255, 0)';
}
});
Please note, that INPUT
has to be all caps.

491 PointsWhat are the "let" and "(e)=>" keywords? And what is event listener? Which JavaScript course in the treehouse goes over these things? I already have gone over the first two JavaScript courses in the treehouse and none of those courses have gone over these concepts.
