**1. What is Semantic HTML?**

Semantic HTML refers to the use of HTML tags that convey the meaning and structure of web content. Unlike generic tags like `<div>` and `<span>`, semantic tags provide context and enhance accessibility, SEO, and readability.

*Example:*
- `<article>`: Represents a self-contained piece of content.
- `<section>`: Defines a section within a document.
- `<header>`: Denotes the introductory content or navigational links.

**2. Why Use Semantic HTML?**

**Enhanced Accessibility**
- Helps screen readers understand the structure and purpose of content.
- Improves navigation for users with disabilities.

**Improved SEO**
- Search engines use semantic tags to better index and rank your content.
- Meaningful tags provide clearer information about the page’s structure.

**Better Maintainability**
- Code is easier to read and manage.
- Clearly defined sections help developers quickly understand the layout.

*Example:*
```html
<article>
  <header>
    <h1>Understanding Semantic HTML</h1>
    <p>Published on May 23, 2024</p>
  </header>
  <section>
    <h2>Introduction</h2>
    <p>Semantic HTML helps create meaningful web content...</p>
  </section>
</article>
```

**3. Key Semantic Elements**

**<header>: The Introductory Section**
- Contains introductory content or navigational links.
- Typically includes a logo, navigation menu, and heading.

*Example:*
```html
<header>
  <h1>My Website</h1>
  <nav>
    <ul>
      <li><a href="#home">Home</a></li>
      <li><a href="#about">About</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
  </nav>
</header>
```

**<main>: The Main Content**
- Represents the dominant content of the <body>.
- Only one <main> element is allowed per page.

*Example:*
```html
<main>
  <article>
    <h2>Welcome to My Blog</h2>
    <p>Here is where I share my thoughts...</p>
  </article>
</main>
```

**<footer>: The Concluding Section**
- Contains footer content like contact info, legal links, and social media links.
- Usually found at the bottom of the page.

*Example:*
```html
<footer>
  <p>&copy; 2024 My Website</p>
  <nav>
    <ul>
      <li><a href="#privacy">Privacy Policy</a></li>
      <li><a href="#terms">Terms of Service</a></li>
    </ul>
  </nav>
</footer>
```

**<article>: Self-Contained Content**
- Represents a self-contained composition in a document.
- Can be independently distributed or reused.

*Example:*
```html
<article>
  <h2>Understanding Web Standards</h2>
  <p>Web standards are guidelines and specifications...</p>
</article>
```

<body>
  <header>
    <h1>My Blog</h1>
    <nav>
