In Java Script we can create a "to-do list" to organize and prioritize your tasks. so today we discuss how to create to do list using css and java script

How To Create To Do Lists Using CSS And JavaScript

Create The To Do List
Step 1
: Create index.html and implement below code.

<div id="myDIV" class="header">
    <h2 style="margin:5px">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: Now implement CSS code to style the header and the list
<style>
    body {
        margin: 0;
        min-width: 250px;
    }

    /* 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;
        list-style-type: none;
        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: tomato;
        color: black;
    }

    /* Style the header */
    .header {
        background-color: tomato;
        padding: 30px 40px;
        color: black;
        text-align: center;
    }

    /* Clear floats after the header */
    .header:after {
        content: "";
        display: table;
        clear: both;
    }

    /* Style the input */
    input {
        margin: 0;
        border: none;
        border-radius: 0;
        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;
        border-radius: 0;
    }

    .addBtn:hover {
        background-color: #bbb;
    }
</style>
 

Step 3: Now Implement java script to add list and delete list items.

<script>
    // 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";
            }
        }
    }
</script>
