    My To-Do List

+-----------------------------+

| Enter a new task |

+-----------------------------+

[ Add Task ]

☐ Learn HTML

☐ Practice CSS

☑ Build Portfolio Website

☐ Learn JavaScript

All | Active | Completed

📌 Features

✅ Add Task

Users can type a task and click the Add Task button.

Example HTML:


Add Task

✅ Display Task List

Each task will be added dynamically using JavaScript.

✅ Add Task Using JavaScript

const addBtn = document.getElementById("addBtn");

const taskInput = document.getElementById("taskInput");

const taskList = document.getElementById("taskList");

addBtn.addEventListener("click", () => {

const task = taskInput.value;

if(task === "") return;

const li = document.createElement("li");

li.textContent = task;

taskList.appendChild(li);

taskInput.value = "";

});

✅ Delete Task

Each task should have a Delete button.

Example:

•
Learn JavaScript
Delete

✅ Mark Task as Completed

Example JavaScript

li.addEventListener("click", () => {

li.classList.toggle("completed");

});

Example CSS

.completed {

text-decoration: line-through;

opacity: .6;

}

✅ Edit Task

Allow users to update an existing task.

Example:

const updatedTask = prompt("Edit task:");

if(updatedTask) {

li.firstChild.textContent = updatedTask;

}

✅ Search Tasks

Filter tasks based on the entered keyword.

✅ Filter Tasks

Create three buttons: All, Active, Completed

Users can switch between: All Tasks, Completed Tasks, Pending Tasks

✅ Save Tasks in Local Storage

localStorage.setItem("tasks", JSON.stringify(tasks));

Load tasks when the page opens.

const savedTasks = JSON.parse(localStorage.getItem("tasks"));

This ensures tasks remain available even after refreshing the browser.
