How the Web Works & What is HTML?

This is the first beginner-level post of our Complete HTML Course (Beginner to Advanced). If you understand this post clearly and practice the examples, HTML will stop feeling confusing and start feeling logical.

Learn HTML from scratch. Understand how the web works, HTML structure, elements, tags and attributes with live editable examples. Perfect for beginners.

Many beginners fail not because HTML is hard, but because they skip fundamentals. This post focuses on strong basics, real explanations, and live practice.

In this post, you will deeply understand: how the web actually works, what HTML really is and what it is not, the correct HTML document structure, and elements, tags, and attributes with live editable examples.

Lesson 1: How the Web Works & What HTML Really Does

When you open a website, a lot happens behind the scenes. Understanding this process will instantly make HTML easier.

How a Website Loads (Step-by-Step Reality)

You type a website URL in the browser
The browser contacts a DNS server to find the website IP
The browser sends a request to the web server
The server responds with HTML files
The browser reads HTML from top to bottom
CSS styles the HTML
JavaScript adds interactivity

Important: The browser cannot style or animate anything until HTML is loaded. HTML is the foundation.

Info!
If your HTML structure is weak, CSS layouts break and JavaScript behaves unexpectedly.

What HTML Is (And What It Is Not)

HTML stands for HyperText Markup Language. HTML describes content. It does not calculate, loop, or make decisions.

Think of HTML as the skeleton of a webpage. CSS is the skin and design. JavaScript is the brain.

Live Example: Your First HTML Page

Edit the code, run it, and observe how the browser responds. This habit will make you faster than most beginners.

<!DOCTYPE html>
<html>
  <head>
    <title>My First HTML Page</title>
  </head>
  <body>
    <h1>Hello HTML</h1>
    <p>This is my first webpage.</p>
  </body>
</html>

Warning!
Never skip the DOCTYPE. It ensures modern browser behavior.

Lesson 2: HTML Document Structure (Deep Understanding)

Every professional website follows a standard structure. This structure helps browsers, SEO, accessibility tools, and developers.

Why Structure Matters

Search engines understand your page better
Screen readers work correctly
Layouts remain predictable

HTML Structure Example

<!DOCTYPE html>
<html>
<head>
  <title>Structure Example</title>
</head>
<body>
  <h2>Main Content</h2>
  <p>This content is visible on the page.</p>
</body>
</html>

<!DOCTYPE html> tells browser this is HTML5
<html> wraps the entire page
<head> stores metadata and SEO info
<body> holds visible content

Warning!
Do not place images, text, or buttons inside the head tag. They will not render properly.

Lesson 3: HTML Elements, Tags & Attributes (Core Concept)

If this lesson clicks, HTML will feel simple forever.

HTML Elements Explained

An element has three parts: opening tag, content, closing tag.

<p>This is a paragraph element</p>

Some elements are self-closing like images and inputs.

HTML Attributes (Extra Power)

<img src="https://cdn.maxoncodes.com/maxoncodes.jpg" alt="Sample Image">

src defines the file location
alt improves accessibility and SEO

Tip!
Always write meaningful alt text. It helps users and search engines.

Common Beginner Mistakes (Avoid These)

Trying to memorize instead of understanding
Skipping live practice
Ignoring structure rules
Forgetting accessibility
