Explanation

  1. HTML Structure:
    • The HTML structure includes a container with an input field for new tasks, a button to add tasks, and an unordered list to display the tasks.
  2. CSS Styling:
    • The CSS styles the container, input elements, task list, and buttons for a clean and modern look.
    • Completed tasks are styled with a line-through effect and gray color to indicate they are done.
  3. JavaScript Functionality:
    • The JavaScript handles adding new tasks, toggling the completion status of tasks, and deleting tasks.
    • Event listeners are set up for the add task button and the enter key to add tasks.
    • The addTask function creates new list items with the task text and a delete button.
    • The toggleComplete function toggles the completed class on the task item to mark it as completed or not.

This setup provides a basic task management application where users can add, complete, and delete tasks. You can expand it by adding more features such as editing tasks, saving tasks to local storage, or categorizing tasks.
