Answer 1

look this code, with it you can use a class attribute for a HTMLColletion

  var eles = document.getElementsByClassName('className');
    for (let i = 0; i < eles.length; i++) {            
            eles[i].addEventListener('click',function(){
                // code ex. eles[i].querySelector(".contenedor").classList.toggle('ocultar');
                // code here...
            })

    }
