var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
        if(!this.classList.contains("active")) {
            closeAccordions();
        }
        this.classList.toggle("active");
        this.nextElementSibling.classList.toggle("show");
  }
}

function closeAccordions() {
    for (i = 0; i < acc.length; i++) {
        acc[i].classList.remove("active");
        acc[i].nextElementSibling.classList.remove("show");

    }
