**How to Validate:**
* Use the [W3C Validator](https://validator.w3.org/).
* Paste your HTML code or upload your file for analysis.

## Meta Tags in HTML
Meta tags provide metadata about an HTML document and are placed inside the <head> element.

**Common Meta Tags:**
1. <meta charset="UTF-8"> - Specifies character encoding.
2. <meta name="viewport" content="width=device-width, initial-scale=1.0"> - Optimizes for mobile devices.
3. <meta name="description" content="A brief description of the page"> - Helps with SEO.
4. <meta name="author" content="Joey Ovey"> - Specifies the author.
5. <meta http-equiv="refresh" content="30"> - Refreshes the page every 30 seconds.

## HTML Headings (h1-h6)
HTML supports six levels of headings (``<h1>`` to ``<h6>``). These define the structure and hierarchy of content.
    
* ``<h1>``: Main title. A webpage should only contain one ``<h1>`` for semantic structure.
* ``<h2>`` to ``<h6>``: Subheadings.
    

## Block-Level Elements
Block-level elements start on a new line and take up the full width.

**Examples:**

* ``<div>``: Used as a container.
* ``<p>``: Represents a paragraph.
    
## Inline-Level Elements
Inline elements do not start on a new line and only take up as much width as necessary.

**Examples:**
* ``<span>``: Used for styling inline content.
* ``<a>``: Represents a hyperlink.

## HTML Entities
HTML entities represent reserved characters or symbols.

**Examples:**
* ``&lt;`` - < (less than).
* ``&gt;`` - > (greater than).
* ``&amp;`` - & (ampersand).
* ``&quot;`` - " (double quotes).
* ``&copy;`` - © (copyright symbol).


## Address Element
The ``<address>`` element defines contact information.
**Code example:**    
```
<address>
  Contact us at: <a href="mailto:support@joey.com">support@joey.com</a>
</address>
```

## Comments
HTML comments are ignored by the browser and used for documentation.
**Syntax:**
```
<!-- This is a comment -->
```
 
## Lists
* **Ordered List ``(<ol>):``** Displays items in a numbered format.
    
**Example:**    
```
<ol>
  <li>Item 1</li>

</ol>
```
* **Unordered List ``(<ul>)``:** Displays items in a bulleted format.

**Example:** 
```
<ul>
  <li>Item A</li>
  <li>Item B</li>
</ul>
```    

* **Description List ``(<dl>)``:** Displays terms and descriptions.

**Example:**
```
<dl>
  <dt>HTML</dt>
    <dd>A markup language for creating web pages.</dd>
  <dt>CSS</dt>
    <dd>A Casecading Stylesheet for creating web pages </dd>
  <dt>Javascript</dt>
    <dd>A programming language for manipulating HTML and CSS elements on the web pages.</dd>
</dl>
```

## Links
**Types of Links:**
* **Absolute Reference:** Specifies the full URL to another website.

```
<a href="https://www.blockfuselabs.com">Visit Blockfuse Labs</a>
```

The ``<img>`` element embeds images in an HTML document.

**Example:**
    
```
<img src="image.jpg" alt="Description of the image">
```

## ``<code>`` Element

The ``<code>`` element represents computer code.
**Example:**
```
<code>
    console.log('Hello, World!');
    <h1>My journey in Web Development</h1>
</code>
```    

<div>
    <h1>Web Development, 2025</h1>
    <p>Learn a digital skill to be a boss of yourself</p>

## Tables
Tables are comprises of rows and columns where we organize our data.
**Elements:**

* **Reset:** Clears all fields.
* **Post:** Secure data submission.
* **FormMethod:** Defines HTTP method.


## HTML Semantic Elements
HTML semantic elements clearly describe their meaning and purpose, making the structure of a webpage easier to understand for both developers and search engines. They improve accessibility, SEO, and code readability by defining the roles of different parts of a webpage.

**Key Semantic Elements:**

* ``<section>``: Used to group related content under a thematic section. Ideal for dividing a page into logical segments.
Example:

```
<section>
  <h2>About Us</h2>
  <p>We are a tech company...</p>
</section>
```

* ``<article>``: Represents a self-contained piece of content that can stand alone (e.g., blog post, news article).
**Example:**

```
<article>
  <h3>Latest News</h3>
  <p>New product launch next week...</p>
</article>
```
    
* ``<aside>``: Contains supplementary content, such as sidebars, ads, or links that are related to the main content.
**Example:**

```
<aside>
  <h4>Related Articles</h4>
  <ul>
    <li><a href="#">Article 1</a></li>
  </ul>
</aside>
```
* ``<details>`` and ``<summary>``: Used for creating collapsible content sections, improving interactivity and saving space.
**Example:**

```
<details>
  <summary>Read More</summary>
  <p>Additional information...</p>
</details>
```
* ``<time>``: Represents specific dates or times, often used for events or timestamps.
**Example:**

```
<time datetime="2025-01-27">January 27, 2025</time>
```
* ``<header>``: Defines the introductory section of a page or an article. Typically includes headings, logos, or navigation links.
**Example:**

```
<header>
  <h1>Website Title</h1>
  <nav>
    <a href="#">Home</a>
    <a href="#">About</a>
  </nav>
</header>
```
* ``<footer>``: Represents the closing section of a document, article, or page. Often contains copyright information or links.
**Example:**

```
<footer>
  <p>&copy; 2025 Your Website</p>
</footer>
```
* ``<nav>``: Specifies a navigation section containing links to other parts of the site or external resources.
**Example:**

```
<nav>
  <a href="/">Home</a>
  <a href="/contact">Contact</a>
</nav>
```
* ``<main>``: Represents the main content of a webpage, excluding headers, sidebars, and footers.
**Example:**

```
<main>
  <h1>Welcome to Our Site</h1>
  <p>Explore our services...</p>
</main>
```
* ``<figure>`` and ``<figcaption>``: Used for adding images, diagrams, or illustrations with optional captions.
**Example:**

```
<figure>
  <img src="image.jpg" alt="Sample Image">
  <figcaption>Image description.</figcaption>
</figure>
```
**Benefits of Semantic HTML:**
* **Improved Accessibility:** Helps screen readers interpret content more effectively.
* **SEO Optimization:** Provides better content indexing for search engines.
* **Cleaner Code:** Makes the structure logical and easier to maintain.
* **Consistency:** Establishes a standard way to define elements.

By using semantic elements, developers create meaningful layouts that enhance both user experience and functionality.
