INTERACTION WITH THE DOM

let section = document.getElementsByTagName('section')[0]; let inputList = document.getElementsByTagName('text'); section.addEventListener('click', (e) => { if (e.target.tagName === 'inputList') { e.target.style.backgroundColor = 'rgb(255, 255, 0)'; }else{ e.target.style.display = 'none';

 }

});

Hello Fidelis!

For this challenge we're trying to change the existing event into a conditional that only changes INPUT elements. Where you have inputList in the conditional, you'll want to replace with INPUT (all caps). That change will be enough to pass the challenge, but there are some other ways you could improve your code to be practicing for future projects!

  • The inputList variable is trying to grab something that doesn't exist, if you wanted to keep the variable I'd suggest changing it to let inputList = document.getElementsByTagName('input');. However, the input elements are contained in the section block, which means there's actually no need to define a variable for it at all.
  • Deleting the code comment at the bottom that serves no purpose anymore.
  • Making sure to use proper indents and spacing to make your code more readable.

Hope this helps!
