Simple To-Do List with CRUD Functionality using HTML, CSS, and JavaScript

We’ve all been there — juggling a million tasks and trying to keep track of them. That’s where a To-Do List comes in handy. Whether you’re managing your daily chores, work assignments, or study plans, a well-structured To-Do list can be a lifesaver.

In this blog post, we’ll walk through creating a To-Do List web application with CRUD features (Create, Read, Update, and Delete) using plain HTML, CSS, and JavaScript. The app is user-friendly and efficient, and it will help you organise tasks with ease. You’ll be able to add, edit, delete, and mark tasks as completed — all in one place.

Key Features of the To-Do List:

• Create: Add new tasks to the list.
• Read: View the list of tasks.
• Update: Edit existing tasks.
• Delete: Remove tasks from the list.
• Mark Completed: Strike-through tasks when they’re done.
