Building Your First Web Application: A Step-by-Step Tutorial

From Zero to Web App

In this tutorial, we'll walk through building a simple web application from scratch. No prior experience required!

What We'll Build

A personal task manager where you can:

• Add new tasks
• Mark tasks as complete
• Delete tasks
• Filter by status

Technologies Used

• HTML — Structure
• CSS — Styling
• JavaScript — Interactivity

Step 1: Set Up the HTML

Create a basic HTML file with a form for adding tasks and a list to display them.

Step 2: Style with CSS

Add modern styling with flexbox layout, custom colors, and responsive design.

Step 3: Add JavaScript Logic

Implement the core functionality:

// Add a new task
function addTask(title) {
    tasks.push({ title, completed: false });
    renderTasks();
}

Step 4: Add Local Storage

Persist your tasks so they survive page refreshes.

Next Steps

Once you're comfortable with the basics, explore:

• React or Vue.js for building complex UIs
• Node.js for server-side development
• Databases for persistent storage
