HTML (HyperText Markup Language)
Introduction to HTML
HTML (HyperText Markup Language) is the standard markup language used to create and structure content on websites and web pages. It provides the basic structure of a webpage by defining elements such as headings, paragraphs, images, links, tables, forms, videos, and other types of content.
HTML is one of the fundamental technologies of web development, along with CSS and JavaScript. While HTML provides the structure of a webpage, CSS is generally used to control its appearance and layout, and JavaScript is used to add interactivity and dynamic functionality.
HTML is beginner-friendly and forms the foundation of almost every website available on the internet. Whether it is a simple personal webpage, a business website, an educational portal, or a complex web application, HTML plays an important role in organizing and presenting web content.
What is HTML?
HTML stands for HyperText Markup Language.
It is called a markup language because it uses predefined elements and tags to describe the structure and meaning of content rather than functioning as a traditional programming language.
For example, HTML can tell a browser:
This is a heading.
This is a paragraph.
This is an image.
This is a hyperlink.
This is a list.
This is a form.
This is a table.
This section contains navigation.
A web browser reads the HTML document and renders the structured content as a webpage.
Basic Structure of an HTML Document
A typical HTML document contains several important parts:
<!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>Explanation
<!DOCTYPE html>
Defines the document as an HTML5 document.
<html>
The root element of the HTML document.
<head>
Contains information about the webpage, such as its title, metadata, stylesheets, and other resources.
<title>
Defines the title displayed in the browser tab.
<body>
Contains the visible content of the webpage.
HTML Tags and Elements
HTML uses tags to define different types of content.
Examples include:
<h1>– Main heading<h2>– Secondary heading<p>– Paragraph<a>– Hyperlink<img>– Image<ul>– Unordered list<ol>– Ordered list<li>– List item<table>– Table<form>– Form<button>– Button<div>– Generic block container<span>– Generic inline container
Most HTML elements have an opening and closing tag.
Example:
<p>This is a paragraph.</p>Some elements, such as <img>, do not require a closing tag.
HTML Headings
HTML provides six levels of headings, from <h1> to <h6>.
<h1>Main Heading</h1>
<h2>Section Heading</h2>
<h3>Subsection Heading</h3>Headings help organize webpage content into a logical hierarchy.
They are also important for SEO and accessibility, because search engines and assistive technologies can use the document structure to understand the content.
HTML Paragraphs
The <p> element is used to create paragraphs.
<p>
HTML is used to structure content on web pages.
</p>Paragraphs make written website content easier to read and organize.
HTML Links
Links allow users to navigate between webpages and resources.
Example:
<a href="https://example.com">Visit Website</a>Links are one of the most important features of the web because they connect different pages and resources.
HTML Images
Images can be added to webpages using the <img> element.
<img src="image.jpg" alt="Website image">The alt attribute provides alternative text describing the image. This is useful for accessibility and can also help search engines understand image content.
HTML Lists
HTML supports different types of lists.
Unordered List
<ul>
<li>HTML</li>
<li>CSS</li>
<li>JavaScript</li>
</ul>Ordered List
<ol>
<li>Learn HTML</li>
<li>Learn CSS</li>
<li>Learn JavaScript</li>
</ol>Lists are useful for menus, features, instructions, services, and other structured information.
HTML Tables
Tables are used to represent structured data in rows and columns.
Example:
<table>
<tr>
<th>Name</th>
<th>Course</th>
</tr>
<tr>
<td>Student 1</td>
<td>Web Development</td>
</tr>
</table>Tables can be useful for displaying schedules, pricing information, reports, product details, and other tabular data.
HTML Forms
Forms allow websites to collect information from users.
Common form elements include:
Text fields
Email fields
Password fields
Radio buttons
Checkboxes
Dropdown menus
Submit buttons
Text areas
Example:
<form>
<label>Name:</label>
<input type="text">
<label>Email:</label>
<input type="email">
<button type="submit">Submit</button>
</form>Forms are commonly used for:
Contact forms
Registration
Login pages
Feedback
Online applications
Search
Surveys
Semantic HTML
Modern HTML provides semantic elements that describe the purpose of different sections of a webpage.
Examples include:
<header><nav><main><section><article><aside><footer>
Example:
<header>
<h1>My Website</h1>
</header>
<nav>
<a href="#">Home</a>
<a href="#">About</a>
</nav>
<main>
<section>
<h2>About Us</h2>
<p>Information about our company.</p>
</section>
</main>
<footer>
<p>Copyright 2026</p>
</footer>Semantic HTML makes webpages easier for developers, search engines, and assistive technologies to understand.
HTML5 Features
HTML5 introduced many improvements to web development, including semantic elements and native support for multimedia.
Important HTML5 features include:
Semantic Elements
Elements such as <header>, <nav>, <section>, <article>, and <footer>.
Audio and Video
<video controls>
<source src="video.mp4" type="video/mp4">
</video>Canvas
The <canvas> element provides an area that scripts can use for drawing graphics and visual content.
Improved Forms
HTML provides input types such as:
emailnumberdatetelurlsearch
Responsive Design Support
HTML works together with CSS to create websites that adapt to different screen sizes.
HTML and CSS
HTML and CSS work together but perform different roles.
HTML = Structure
CSS = Presentation
HTML defines what content exists on the page, while CSS controls how that content looks.
For example, HTML may create a heading:
<h1>Welcome</h1>CSS can then control its:
Font
Size
Spacing
Position
Layout
Appearance
This separation helps developers create maintainable websites.
HTML and JavaScript
HTML provides the structure, while JavaScript can add behavior and interaction.
For example, HTML can create a button:
<button>Click Me</button>JavaScript can make that button perform an action when the user clicks it.
Together, HTML, CSS, and JavaScript form the basic technology stack used to build many modern websites and web applications.
