## Overview

This is a small browser-based to-do app. A user enters a task and clicks Add; `script.js` validates the input, creates a checkbox-and-label item, appends it to the task list, and wires its checkbox to toggle completion styling. The app also initializes three existing tasks and hides the navigation and sidebar when the hamburger button is clicked. No persistence is evident in the sampled code. The tree names `index.html` and `style.css`, but their contents were not sampled, so their specific markup and styling are not represented.

Main entry points: [`script.js`](https://github.com/aman-codemaster/todo-app/blob/main/script.js) (To-do logic), [`index.html`](https://github.com/aman-codemaster/todo-app/blob/main/index.html) (Task checkbox)
