HTML vs CSS vs JavaScript — What’s the Difference?

✅ Understand the core building blocks of the web in under 5 minutes.

📌 What is HTML?

HTML stands for HyperText Markup Language.

It’s the skeleton of a webpage. It tells the browser what content to display — like headings, paragraphs, images, buttons, and links.

🧱 Think of HTML as:
“The structure of your house — the bricks, walls, and doors.”

CSS stands for Cascading Style Sheets.

It styles your HTML — colors, fonts, spacing, layouts, and animations.

🎨 Think of CSS as:
“The paint, furniture, and decoration in your house.”

h1 {
  color: navy;
  font-size: 36px;
  text-align: center;
}

JavaScript (often called JS) makes your website interactive.

It handles logic, animations, form validation, sliders, menus, and more.

⚙️ Think of JavaScript as:
“The electricity in your house — turning on lights, opening garage doors, adjusting the thermostat.”

document.querySelector("h1").addEventListener("click", function() {
  alert("You clicked the heading!");
});
