const toggleList = document.getElementById('toggleList');
const listDiv = document.querySelector('.list');
const descriptionInput = document.querySelector('input.description');
const descriptionP = document.querySelector('p.description');
const descriptionButton = document.querySelector('button.description');
const listUl = listDiv.querySelector('ul');
const addItemInput = document.querySelector('input.addItemInput');
const addItemButton = document.querySelector('button.addItemButton');
listUl.addEventListener('click', (event) => {
if (event.target.tagName == 'BUTTON') {
if(event.target.className == 'remove'){
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
if(event.target.className == 'up'){
let li = event.target.parentNode;
let prevLi = li.previousElementSibling;
let ul = li.parentNode;
if(prevLi){
ul.insertBefore(li, prevLi);
}
}
if(event.target.className == 'down'){
let li = event.target.parentNode;
let nextLi = li.nextElementSibling;
let ul = li.parentNode;
if(nextLi){
ul.insertAfter(li, nextLi);
}
}
}
});
