Introduction

What is HTML?

HTML serves as a markup language that structures content on the web. Its tags define various elements on a webpage, from headings and paragraphs to links and images, providing a structured layout for browsers to interpret and display.

Understanding HTML Tags

HTML operates through tags enclosed in angle brackets (< >), each serving a specific purpose:

<html>: Defines the document as an HTML file.
<head>: Contains metadata about the document, like its title.
<body>: Encloses the visible content on the webpage.
<h1> to <h6>: Denote headings of different levels.

Structure of an HTML Document

An HTML document follows a basic structure:

<!DOCTYPE html>
<html>
  <head>
    <title>Your Title Here</title>
  </head>
  <body>
    <h1>Main Heading</h1>
    <p>Paragraphs of text...</p>
    <img src="image.jpg" alt="Description of Image">
    <a href="https://www.example.com">Link Text</a>
  </body>
</html>

Significance of Semantic HTML

Semantic HTML goes beyond mere tags; it assigns meaning to the content. By using semantic tags like <header>, <footer>, <nav>, and <article>, developers provide context to the webpage's structure, improving accessibility and SEO.

<header>
  <h1>Website Title</h1>
  <nav>
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Services</a></li>
    </ul>
  </nav>
</header>
<article>
  <h2>Article Title</h2>
  <p>Article content...</p>
</article>
<footer>
  <p>Contact information...</p>
</footer>

Conclusion

In conclusion, understanding Semantic HTML is crucial for developers. By employing semantic tags, you enhance your website's structure, making it more accessible and search-engine friendly. Mastering these basics is the first step toward creating efficient and impactful web content.
