This is my first post here in Stack Overflow. Apologies if I'm not doing it in the right way.
OK so I'm doing this To Do List as a second project but I can't find a solution yet.
I tried creating a node list, then going through the whole list, creating a new element and adding it to every item. Problem is, only the icon I added to the first LI in the HTML file is showing.
Am I doing it in the wrong way?
Any help is really appreciated!
This is how it looks like so far
HTML:
<title>To Do List</title>
</head>
<body>
<div id="box">
<div id="header">
<h1 id="title">To Do List</h1>
<span onclick="newElement()" id="addButton">+</span>
<input type="text" id="newTask" class="hideMe" class="showMe" placeholder="New task...">
</div>
<div id="tasks">
<ul id="items">
<li class="checked">Go to the gym</li>
<button class="remove" class="hideMe" class="showMe"><i class="fa fa-trash"></i></button>
<li>Keep studying web development</li>
<li>1</li>
</ul>
</div>
</div>
<script src="js/toDoList.js"></script>
</body>

JS:
const addButton = document.getElementById("addButton");
const newTaskInput = document.getElementById("newTask")
const removeButton = document.getElementsByClassName("remove");
var myNodeList = document.getElementsByTagName("LI");
function main() {
for (let i = 0; i < myNodeList.length; i++) {
let span = document.createElement("SPAN")
span.className = "remove";
span.appendChild(removeButton);
myNodeList[i].appendChild(span);
}
}
main();
