How to create a simple to-do list with HTML, CSS, and JS

To-do lists are the backbone of productivity, and in this tutorial, we’ll walk through the process of creating one from scratch using just HTML, CSS, and JavaScript. This minimalist approach ensures accessibility and simplicity, making it perfect for beginners and seasoned developers. By the end of this answer, we'll have a functional to-do list that we can customize to suit our needs. So, let’s jump in and explore the fundamentals of web development as we craft our to-do list.

In order to create a simple to-do list, we have to follow the following four steps:

Step 1: Add HTML

Explanation

  • Line 1: We make a div that acts as a container for our to-do list.

  • Lines 2–5: We make a div for the new task in which the user writes the name of the task, and at the end, it has the “add” button.

  • Line 6: We create a div for the written tasks.

Step 2: Add CSS

Explanation

  • Lines 1–22: We add the styling for the container.

  • Lines 23–58: We add the styling for the tasks input field and the add “Task” button.

  • Lines 59–94: We add the styling for the tasks which we have added.

Step 3: Add JavaScript

Explanation

  • Lines 3–7: We write a function that states that if a user doesn’t enter any task and presses the “Add” button, then an alert message is generated which states that enter the task.

  • Lines 9–19: If the user enters a task, then we have to decide what to do with the task. We use the innerhtml to display all the information on the web page.

  • Lines 21–26: We add a “Delete” button which can be found after every task.
