How TO - The To Do List
Learn how to create a "to-do list" with CSS and JavaScript.
The To Do List
Use CSS and JavaScript to create a "to-do list" to organize and prioritize your tasks.
Create The To Do List
Step 1) Add HTML:
Example
<div id="myDIV" class="header">
  <h2>My To Do List</h2>
  
<input type="text" id="myInput" placeholder="Title...">
  <span 
onclick="newElement()" class="addBtn">Add</span>
</div>
<ul id="myUL">
  <li>Hit 
the gym</li>
  <li class="checked">Pay bills</li>
  
<li>Meet George</li>
  <li>Buy eggs</li>
  <li>Read a 
book</li>
  <li>Organize office</li>
</ul>
Step 2) Add CSS:
Style the header and the list:
Example
/* Include the padding and border in an element's total width and height */
* {
    box-sizing: border-box;
}
/* Remove margins and padding from the list */
ul {
    
margin: 0;
    padding: 0;
}
/* Style the list 
items */
ul li {
    
cursor: pointer;
    position: relative;
    
padding: 12px 8px 12px 40px;
    background: #eee;
    
font-size: 18px;
    transition: 0.2s;
    /* 
make the list items unselectable */
    -webkit-user-select: none;
    
-moz-user-select: none;
    -ms-user-select: none;
    
user-select: none;
}
/* Set all odd list items to a different 
color (zebra-stripes) */
ul 
li:nth-child(odd) {
    background: #f9f9f9;
}
/* Darker background-color on hover */
ul li:hover {
    background: #ddd;
}
/* When 
clicked on, add a background color and strike out text */
ul 
li.checked {
    background: #888;
    
color: #fff;
    text-decoration: line-through;
}
/* Add a "checked" mark when clicked on */
ul li.checked::before {
    content: '';
    
position: absolute;
    border-color: #fff;
    
border-style: solid;
    border-width: 0 2px 2px 0;
    
top: 10px;
    left: 16px;
    
transform: rotate(45deg);
    height: 15px;
    
width: 7px;
}
/* Style the close button */
.close {
    
position: absolute;
    right: 0;
    
top: 0;
    padding: 12px 16px 12px 16px;
}
.close:hover {
    background-color: #f44336;
    
color: white;
}
/* Style the header */
.header {
    background-color: #f44336;
    
padding: 30px 40px;
    color: white;
    
text-align: center;
}
/* Clear floats after the header */
.header:after {
    
content: "";
    display: table;
    
clear: both;
}
/* Style the input */
input {
    
border: none;
    width: 75%;
    
padding: 10px;
    float: left;
    
font-size: 16px;
}
/* Style the "Add" button */
.addBtn {
    padding: 10px;
    
width: 25%;
    background: #d9d9d9;
    
color: #555;
    float: left;
    
text-align: center;
    font-size: 16px;
    
cursor: pointer;
    transition: 0.3s;
}
.addBtn:hover {
    
background-color: #bbb;
}
Step 3) Add JavaScript:
Example
// Create a "close" button and append it to each list item
var myNodelist = document.getElementsByTagName("LI");
var i;
for (i = 
0; i < myNodelist.length; i++) {
  var span = document.createElement("SPAN");
 
var txt = document.createTextNode("\u00D7");
  span.className = "close";
 
span.appendChild(txt);
  myNodelist[i].appendChild(span);
}
// Click on a close button to hide the current list item
var 
close = document.getElementsByClassName("close");
var i;
for (i = 
0; i < close.length; i++) {
  close[i].onclick = function() {
    var div = 
this.parentElement;
    div.style.display = "none";
  }
}
// Add a "checked" symbol when clicking on a list item
var list 
= document.querySelector('ul');
list.addEventListener('click', function(ev) 
{
  if (ev.target.tagName === 'LI') {
    ev.target.classList.toggle('checked');
 
}
}, false);
// Create a new list item when clicking on the "Add" 
button
function newElement() {
  var li = 
document.createElement("li");
  var inputValue = document.getElementById("myInput").value;
 
var t = document.createTextNode(inputValue);
  li.appendChild(t);
  if (inputValue 
=== '') {
    alert("You must write something!");
  } else {
   
document.getElementById("myUL").appendChild(li);
  }
 
document.getElementById("myInput").value = "";
  var span = 
document.createElement("SPAN");
  var txt = document.createTextNode("\u00D7");
 
span.className = "close";
  span.appendChild(txt);
  li.appendChild(span);
  for (i = 0; i < close.length; i++) {
    close[i].onclick = function() {
     
var div = this.parentElement;
      div.style.display = "none";
    }
  }
}
