Hey friends, today in this blog, you’ll learn how to create a complete Todo List App with crud operations in HTML CSS & JavaScript. Crud operation means to create, read, update, and delete. If you’re an absolute beginner, this todo will be a little bit difficult for you to create.

For beginners, you can try to create this easy Todo List App in JavaScript. In this todo, there are no features for editing and completing tasks so, it will be easy for you to create than the current one.

If you don’t know, the todo list app is a list of things that need to be done or want to be done. This app is generally used to maintain our day-to-day tasks list. Okay, without further delay, let’s back to this project.

You can also delete all tasks at once by clicking on the “Clear All” button.

If you’re curious to view a live demo of it, click here to view it, and for a full video tutorial of this Todo List App in JavaScript, you can watch the given YouTube video.

Video Tutorial of Todo List App in JavaScript

In the above video, you’ve seen the demo of the Todo App, its several features, and how I created it using HTML CSS & JavaScript. I hope you watched the video till the end and learn something new from it.

If you didn’t watch the video completely, I request you to watch it and understand the codes and logic properly else you might get confused later on while creating this todo app or implementing the codes in your projects.

If you liked this todo app and want to get source codes or files, you can easily copy or download them from the bottom of this page. You can also try to build this Notes App in JavaScript to increase your skills even more.

Last, create a JavaScript file with the name of script.js and paste the given codes in your JavaScript file. Remember, you’ve to create a file with .js extension.

Todo List App using HTML CSS & JavaScript

CodingNepal — Wed, 16 Dec 2020 15:58:00 +0000

Hey friends, today in this blog you’ll learn how to create Todo List App using HTML CSS & JavaScript. In the previous blog, I’ve also shared how to create Todo App in JavaScript but in that program when you refresh your webpage, the lists or tasks that you’ve added are also removed.

So today I came with another blog where I create Todo App and the lists or tasks that you add won’t be removed when you refresh the page and in this todo app there are also features of pending tasks number and you can also delete all tasks that you have added on single click.

As you may know, A to-do list is a list of tasks you need to complete or things you want to do and in our design [Todo List App], there is a content box that holds only the input field with some buttons and text. When you entered some characters and click on the plus (+) button, the list will be added to your tasks list and the number of the pending tasks also be updated.

You can also delete each list by clicking on the trash icon, and remember this trash icon only appear on hover on the particular list and delete all tasks with a single click. If you want to see this to-do list app and how it is created then you can watch a full video tutorial on this program [Todo List App in JavaScript].

Video Tutorial of Todo List App in JavaScript

In the video, you have seen the to-do list app and how it is created using HTML CSS & JavaScript. I hope you’ve understood the codes behind creating this program. It may be difficult to understand the JavaScript codes of this program but don’t worry once you download the code files of this program and try with yourself, you’ll easily understand.

You may wonder about how these to-do app tasks remain even after refreshing the webpage right? Well, at first, the tasks you’ve added will store in your browser’s local storage and then these lists are retrieved into an HTML file in the form

tag using JavaScript.

You may feel difficult to understand what I’m saying right? If yes then you’ve to watch the video again and again because in the video I have written the comment of each JavaScript line and tried my best to understand the codes for you.

Todo List App in JavaScript [Source Codes]

To create this program [Todo List App]. First, you need to create three files, HTML File, CSS File, and JavaScript File. After creating these files just paste the following codes into your files. You can also download the source code files of the to-do list app from the given download button.

First, create an HTML file with the name of index.html and paste the given codes in your HTML file. Remember, you’ve to create a file with .html extension.

Minimal To-Do List App using HTML CSS & jQuery

CodingNepal — Wed, 29 Apr 2020 11:13:00 +0000

Hello readers, Today in this blog you’ll learn how to create a Minimal To-Do List using HTML CSS, and Javascript. Previously I have shared a Custom Modal Box using HTML CSS & Javascript, now it’s time to create a To-Do List HTML CSS & jQuery.

Todo is a task management app or program to help you to stay organized and managed your day-to-day. You can add things that you have to do in the whole day, after completing those works you can simply remove that item from the list.

As you can see in the image, this one is a minimal To-Do List Design and it is based on jQuery. There are 3 fields in the program. One field for show list, one is input for insert items, and a plus button to add. When you will type some things and press the add button, then the item will add to the list and visible.

And removing any items from the list, you have to hover on that item and there will a trash icon reveal you have to click that to remove. The whole layout has a minimal design. If you’re feeling difficulty understanding what I am saying. You can watch a full video tutorial on this program (Minimal To-Do List).

Video Tutorial of Minimal To-Do List App

If you are a beginner, you can easily use this To-Do List in your project after changes some codes. If you have basic knowledge of HTML CSS & jQuery you can easily do that.

If you like this program (Minimal ToDo List) and want to get source codes. You can easily get the source codes of this program. To get the source codes you just need to scroll down. And, I believe this To-Do list program helps you a lot.

Minimal To-Do List App [Source Codes]

To create this program (Minimal To-Do List). First, you need to create two Files one HTML File and another one is CSS File. After creating these files just paste the following codes in your file. First, create an HTML file with the name of index.html and paste the given codes in your HTML file. Remember, you’ve to create a file with .html extension.
