If you're starting your journey in web development, learning HTML (HyperText Markup Language) is your first and most important step. HTML serves as the backbone of every website, allowing you to structure content and lay the foundation for more advanced technologies like CSS and JavaScript. In this guide, we’ll explore the basics of HTML to help you kickstart your web development journey.
Basic Structure of an HTML Document
An HTML document follows a standard structure:
DOCTYPE Declaration:
Specifies the version of HTML being used.
Example:
<!DOCTYPE html>
for HTML5.
HTML Element:
The root element that wraps all other content.
Example:
<html> ... </html>
Head Element:
Contains metadata like the title of the page, character set, and links to stylesheets or scripts.
Example:
<head> <title>Page Title</title> </head>
Body Element:
Contains the visible content of the web page.
Example:
<body> <h1>Hello World</h1> </body>
Common HTML Tags
Here are some essential HTML tags every beginner should know:
Headings:
Used to create headings, ranging from
<h1>
(largest) to<h6>
(smallest).Example:
<h1>Main Heading</h1> <h2>Subheading</h2>
Paragraphs:
Used for regular text.
Example:
<p>This is a paragraph.</p>
Links:
Create clickable hyperlinks.
Example:
<a href="https://www.example.com">Visit Example</a>
Images:
Embed images in your web page.
Example:
<img src="image.jpg" alt="Description of Image">
Lists:
Ordered lists (
<ol>
) and unordered lists (<ul>
).Example:
<ul> <li>Item 1</li> <li>Item 2</li> </ul>
Tables:
Organize data into rows and columns.
Example:
<table> <tr> <th>Column 1</th> <th>Column 2</th> </tr> <tr> <td>Data 1</td> <td>Data 2</td> </tr> </table>
Attributes in HTML
HTML elements can have attributes that provide additional information. These are always written in the opening tag.
Examples of Common Attributes:

<a>
tags to define the link’s URL.src: Used in
