<h1> → Heading
<p> → Paragraph
<a> → Link
<img> → Image
<button> → Button
Once you understand tags, elements, attributes, and nesting, you'll be able to start building real webpage structures.

-----
1.24 ₽ · /balance_help<h1>Hello World</h1>
Here:
<h1> → opening tag
Hello World → content
</h1> → closing tag
The complete structure is called an HTML element.
2. HTML Element
An HTML element usually looks like this:
<tag>Content</tag>
For example:
<p>This is a paragraph.</p>
<h2>About Me</h2>
<button>Click Me</button>
Think of an element as a complete building block of a webpage.
3. Opening and Closing Tags
Most HTML elements have both.
<p>Hello</p>
Opening:
<p>
Closing:
</p>
Notice the / in the closing tag.
4. Some Tags Don't Need a Closing Tag
Some HTML elements are void elements.
Example:
<img src="photo.jpg" alt="My photo">
<br>
<hr>
They don't have a separate closing tag.
5. HTML Attributes
Attributes provide additional information about an element.
Example:
<a href="https://example.com">Visit Website</a>
Here:
href="https://example.com" is an attribute.
Another example:
<img src="profile.jpg" alt="Profile photo">
The image has two attributes:
src → location of the image
alt → description of the image
6. Attributes Usually Go Inside the Opening Tag
Correct:
<p class="description">Hello</p>
Incorrect:
<p>Hello</p class="description">
7. Nesting Elements
HTML elements can be placed inside other elements.
Example:
<div>
<h1>My Website</h1>
<p>Welcome to my website.</p>
</div>
Here:
<div>
├── <h1>
└── <p>
The <h1> and <p> elements are inside the <div>.
8. Proper Nesting Matters
Correct:
<p>
Hello <strong>World</strong>
</p>
Incorrect:
<p>
Hello <strong>World</p></strong>
HTML elements should be properly nested.
9. HTML Comments
Comments allow developers to leave notes in their code.
<!-- This is a comment -->
The browser doesn't display the comment as webpage content.
Example:
<!-- Website heading -->
<h1>My Portfolio</h1>
10. A Simple HTML Example
<!DOCTYPE html>
<html>
<head>
<title>My Portfolio</title>
</head>
<body>
<h1>Welcome to My Portfolio</h1>
<p>I am learning web development.</p>
<a href="about.html">About Me</a>
</body>
</html><head> in detail later.
9️⃣ <body>
The <body> contains the main content displayed on the webpage.
For example:
<body>
<h1>Welcome</h1>
<p>This is my website.</p>
</body>
The user can see this content in the browser.
A simple way to remember:
<html>
│
├── <head>
│ → Information about the page
│
└── <body>
→ Visible page content
🔟 <!DOCTYPE html>
You'll usually see this at the beginning of an HTML document:
<!DOCTYPE html>
It tells the browser that the document uses modern HTML standards.
It's a doctype declaration, not an ordinary HTML element.
🌐 Real-World Example
Imagine you're building a portfolio.
You might start with:
<h1>Deepak's Portfolio</h1>
<p>
Welcome to my portfolio website.
</p>
<h2>My Projects</h2>
<p>
Here are some of the projects I have built.
</p>
HTML provides the structure:
Portfolio
↓
Introduction
↓
Projects
↓
Project information
Later, CSS will make this structure visually appealing.
JavaScript can then add interactive behaviour.
🧩 HTML + CSS + JavaScript
Think about a car:
HTML → The structure
Provides the basic parts:
• Body
• Seats
• Wheels
• Dashboard
CSS → The appearance
Controls:
• Colors
• Size
• Design
• Layout
JavaScript → Behaviour
Controls things such as:
• Interactive controls
• Dynamic behaviour
• Responses to user actions
Together, they form the foundation of frontend web development.
🧠 Key Points to Remember
• HTML = HyperText Markup Language
• HTML structures webpage content.
• HTML is a markup language, not a programming language.
• HTML uses elements and tags.
• <head> contains information about the document.
• <body> contains the main visible webpage content.
• <!DOCTYPE html> declares the document type.
• HTML provides structure, CSS provides styling, and JavaScript provides behaviour.

1.45 ₽ · /balance_helpHTML tells the browser what content exists on a webpage and what each piece of content represents.For example, a webpage might contain: • A heading • Paragraphs • Images • Links • Buttons • Lists • Forms • Tables HTML provides the structure for these elements. 2️⃣ HTML Is Not a Programming Language This is an important distinction. HTML is a markup language, not a programming language. HTML describes the structure and meaning of content. For example:
<h1>My Portfolio</h1>
<p>Welcome to my website.</p>
There is no programming logic here.
We're simply telling the browser:
"This is a main heading."and:
"This is a paragraph."JavaScript, on the other hand, can perform programming logic:
let age = 25;
if (age >= 18) {
console.log("Adult");
}
So remember:
• HTML → Structure
• CSS → Appearance
• JavaScript → Behaviour and logic
3️⃣ How HTML Works
HTML uses elements to describe content.
For example:
<h1>Hello World</h1>
The browser interprets this as a heading.
Another example:
<p>Welcome to my website.</p>
The browser interprets this as a paragraph.
The browser then turns the HTML structure into the webpage you see.
4️⃣ HTML Elements
An HTML element commonly consists of:
<tag>Content</tag>
For example:
<p>Hello</p>
Here:
• <p> → Opening tag
• Hello → Content
• </p> → Closing tag
Together, they form an HTML element.
Another example:
<h1>Web Development</h1>
The entire thing is an HTML element.
5️⃣ HTML Tags
A tag is the markup used to define an element.
Examples:
• <h1>
• <p>
• <a>
• <img>
• <button>
Different tags represent different types of content.
For example:
<h1>My Website</h1>
h1 represents a heading.
<p>Hello everyone.</p>
p represents a paragraph.
<button>Login</button>
button represents a button.
6️⃣ A Simple HTML Page
A basic HTML document looks like this:
<!DOCTYPE html>
<html>
<head>
<title>My Website</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is my first webpage.</p>
</body>
</html>
Don't worry if you don't understand everything yet.
We'll learn each part separately.
For now, understand the overall structure.
7️⃣ <html>
The <html> element represents the root of the HTML document.
Most of your HTML page exists inside it.
<html>
...
</html>
Think of it as the outer container of the document.
8️⃣ <head>
The <head> contains information about the webpage that generally isn't displayed as the main page content.
For example:
<head>
<title>My Website</title>
</head>../
means:
Go up one directory.This concept becomes very important as projects become larger. 9️⃣ Common Project Folders As applications become more complex, you'll encounter folders such as: src/ components/ pages/ assets/ images/ styles/ utils/ services/ Their exact purpose depends on the project and framework. For example:
src/
├── components/
├── pages/
├── services/
├── assets/
└── styles/
We'll learn these structures when we start working with React and larger applications.
🔟 A Real-World Project
A simple website might look like:
portfolio/
│
├── index.html
├── about.html
├── contact.html
│
├── css/
│ └── style.css
│
├── js/
│ └── script.js
│
└── images/
├── profile.jpg
└── project1.png
A larger modern application might eventually look more like:
my-app/
│
├── src/
│ ├── components/
│ ├── pages/
│ ├── services/
│ ├── assets/
│ └── styles/
│
├── public/
├── package.json
├── README.md
└── .gitignore
Don't worry about understanding all of these folders yet.
We'll introduce them when we actually need them.
🧠 Key Things to Remember
File → Stores information or code.
Folder → Organizes files.
index.html → Common default/main HTML document.
images/ → Can organize image files.
css/ → Can organize CSS files.
js/ → Can organize JavaScript files.
../ → Moves up one directory in a relative path.
A good project structure keeps code organized and makes applications easier to understand and maintain.Double Tap ❤️ For Part 12 ----- 1.29 ₽ · /balance_help
my-website/
│
├── index.html
├── style.css
├── script.js
│
├── images/
│ ├── logo.png
│ └── profile.jpg
│
└── pages/
├── about.html
└── contact.html
Here:
my-website/
is the main project folder.
Inside it are files and additional folders.
3️⃣ Why Do We Need Project Structure?
Imagine putting every file for a large application into one folder without organization.
You might eventually have:
100+ files
Finding the correct file would become difficult.
A good structure makes it easier to:
Find files
Understand the project
Maintain code
Work with other developers
Scale the application
4️⃣ The Basic Website Structure
For a beginner website, you can start with:
my-website/
│
├── index.html
├── style.css
└── script.js
Each file has a different job.
index.html
Contains the webpage structure.
<h1>My Website</h1>
<p>Welcome to my website.</p>
style.css
Controls the appearance.
h1 {
color: blue;
}
script.js
Adds behaviour.
console.log("Website loaded");
The browser can connect these files together.
5️⃣ The index.html File
You'll see index.html very often.
It is commonly used as the main or default HTML page of a website.
For example:
my-website/
│
└── index.html
When someone visits the main page of a simple website, the server may serve the index.html document.
It's a convention rather than a universal rule for every web application.
6️⃣ Organizing Images
Instead of putting every image directly in the project root, we can create an images folder.
my-website/
│
├── index.html
├── style.css
├── script.js
│
└── images/
├── logo.png
├── laptop.jpg
└── phone.jpg
Then HTML can reference an image inside that folder.
<img src="images/logo.png" alt="Logo">
The path:
images/logo.png
tells the browser where the image is located relative to the HTML file.
7️⃣ Multiple Pages
A website can contain multiple HTML pages.
For example:
my-website/
│
├── index.html
├── about.html
├── contact.html
│
├── css/
│ └── style.css
│
└── images/
└── logo.png
You could have:
index.html → Home
about.html → About
contact.html → Contact
This is a simple way to understand how multi-page websites are structured.
8️⃣ Relative Paths
Understanding file paths is extremely important.
Suppose you have:
project/
│
├── index.html
│
└── images/
└── logo.png
From index.html, you can reference the image using:
<img src="images/logo.png">
Now suppose you have:
project/
│
├── pages/
│ └── about.html
│
└── images/
└── logo.png
From about.html, you need to go up one folder first:
<img src="../images/logo.png">
