Introduction to HTML

In the vast landscape of web development, HTML (Hypertext Markup Language) stands as the foundational building block. It’s the backbone upon which every web page is constructed. This in-depth guide is tailored exclusively for beginners who aspire to master the art of HTML. We will delve deep into the world of HTML, exploring the essential tools, terminologies, coding practices, and the critical concept of semantics.

Chapter 1: Unveiling the HTML Universe

1.1 What is HTML?

HTML, in its essence, is a markup language, not a programming language. It acts as the structural framework for web pages, defining the content’s layout and hierarchy.

1.2 Anatomy of an HTML Document

<!DOCTYPE html>: A declaration that sets the document’s type.
<html>: The root element enclosing all content.
<head>: Metadata and document-related information.
<title>: The title displayed in the browser tab.
<meta>: Information about character encoding, keywords, and descriptions.
<link>: Links external stylesheets for styling.
<script>: Links external JavaScript files or contains inline scripts.
<body>: The container for the visible content.

Chapter 2: Structuring Content

2.1 Headings

HTML offers six levels of headings from <h1> (most important) to <h6> (least important). Mastering heading tags is crucial for organising content effectively.

<h1>Main Heading</h1>
<h2>Subheading</h2>
<h3>Sub-subheading</h3>

2.2 Paragraphs and Text Formatting

Learn to use the <p> element for paragraphs and text formatting tags like <em> (italic) and <strong> (bold) to convey emphasis and importance.

<p>This is an <em>italic</em> and <strong>bold</strong> text example.</p>

2.3 Lists

Master the art of creating unordered lists (<ul>), ordered lists (<ol>), and definition lists (<dl>) to structure content effectively.

</ul>

<ol>
  <li>First</li>
  <li>Second</li>
</ol>

The <a> tag allows you to create hyperlinks. Learn how to link to other web pages or resources within your site.

<a href="https://www.example.com">Visit Example.com</a>

Incorporate images using the <img> element, and understand the importance of the alt attribute for accessibility and SEO.
