Tags in HTML | HTML5 for Web Development - Software Development PDF Download

Introduction

HTML (Hypertext Markup Language) is the backbone of web development. It provides a way to structure and format content on the web. One of the fundamental elements of HTML is tags. Tags are used to define the structure and semantics of a web page. In this article, we'll explore tags in HTML, their usage, and provide simple code examples to help beginners understand their significance.

What are HTML Tags?

HTML tags are elements used to mark up the content within an HTML document. Tags provide structure and meaning to the content and tell web browsers how to display and interpret the information. Each HTML tag is surrounded by angle brackets (<>) and comes in pairs: an opening tag and a closing tag.

Anatomy of an HTML Tag

An HTML tag consists of the following components:

  • Opening Tag: It starts with the less than symbol (<) followed by the tag name and ends with a greater than symbol (>). For example, '<tagname>'.
  • Closing Tag: It starts with the less than symbol (<), followed by a forward slash (/), the tag name, and ends with a greater than symbol (>). For example, '</tagname>'.
  • Content: The actual content that goes between the opening and closing tags.
  • Attributes: Additional information that can be added to the tag to provide extra instructions or properties. Attributes are placed within the opening tag.

HTML Tag Examples

Let's explore some commonly used HTML tags with their code examples, output, and explanations:

Heading Tags

Heading tags ('<h1>' to '<h6>') are used to define headings and subheadings on a webpage. The number represents the importance and hierarchy of the heading, with <h1> being the highest and <h6> being the lowest.

<h1>This is a Heading</h1>

Output:
This is a Heading

Paragraph Tags

Paragraph tags ('<p>') are used to define paragraphs of text on a webpage.

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

Output:
This is a paragraph.

Link Tags

Link tags ('<a>') are used to create hyperlinks that navigate to another webpage or a specific location within the same page.

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

Output:
Visit Example Website

Image Tags

Image tags ('<img>') are used to insert images into a webpage.

<img src="https://edurev.gumlet.io/mage.jpg" alt="Description of the image">

Output:
(The actual image will be displayed in the webpage)

Nesting Tags

HTML tags can be nested within each other to create more complex structures. It's important to ensure proper opening and closing tag pairs to maintain the integrity of the HTML structure.

<div>

  <h2>Welcome to My Website</h2>

  <p>This is a paragraph with a <a href="https://www.example.com">link</a>.</p>

</div>

Output:

Welcome to My Website

This is a paragraph with a link.
