What is HTML?

HTML stands for Hypertext Markup Language. It's the standard markup language used to create web pages. HTML describes the structure of a web page using a series of elements or tags. These elements tell the web browser how to display the content.

HTML was created by Tim Berners-Lee in 1991 as a way to share documents over the internet. Since then, it has evolved through various versions, with HTML5 being the latest standard.

Key Points About HTML:

  • HTML is not a programming language but a markup language used to structure content
  • It uses tags enclosed in angle brackets like <tagname>content</tagname>
  • HTML documents have the file extension .html or .htm
  • HTML can be created and edited using simple text editors
  • It works alongside CSS (for styling) and JavaScript (for interactivity)

Why Use HTML?

You might wonder why HTML is important when there are so many website builders available. Here are some compelling reasons to learn HTML:

  1. Foundation of Web Development: HTML is the starting point for all web development. Even if you use tools like WordPress or Wix, understanding HTML helps you customize your site beyond the default options.

  2. Career Opportunities: Web development is a growing field with excellent job prospects. Learning HTML is the first step toward a career in web development.

  3. Control Over Your Content: With HTML knowledge, you can create exactly what you want without being limited by pre-built templates.

  4. Free to Use: HTML is an open standard that anyone can use without licensing fees or restrictions.

  5. Accessibility: Creating accessible websites (usable by people with disabilities) requires understanding HTML's semantic structure.

  6. Device Compatibility: Proper HTML ensures your content works across different devices and screen sizes.

How to Start with HTML

Getting started with HTML is surprisingly simple. Here's what you need:

Tools Required:

  1. A Text Editor: You can use basic text editors like Notepad (Windows) or TextEdit (Mac), but specialized code editors like Visual Studio Code, Sublime Text, or Atom offer helpful features like color coding and auto-completion.

  2. A Web Browser: Any modern browser like Chrome, Firefox, Safari, or Edge will work to view your HTML pages.

Writing Your First HTML Document:

  1. Open your text editor
  2. Create a new file
  3. Save the file with a .html extension (e.g., mypage.html)
  4. Start writing HTML code

Here's a simple example of an HTML document structure:

 <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First HTML Page</title>
</head>
<body>
    <h1>Hello, World!</h1>
    <p>This is my first HTML page.</p>
</body>
</html>
 
To view this page:
  1. Save the file
  2. Open it with your web browser (double-click the file or use File > Open in your browser)

Congratulations! You've just created your first HTML page.

Basic HTML Tags Explained

HTML consists of various tags that serve different purposes. Let's explore the most important ones:

Document Structure Tags

<!DOCTYPE html>

This declaration defines the document as HTML5. It must appear at the very beginning of the HTML document.

<html></html>

The root element that contains all other HTML elements. The lang attribute specifies the language of the document.

<html lang="en">
  <!-- All other content goes here -->
</html>
<head></head>

Contains meta-information about the document that isn't displayed on the page itself.

<head>
  <meta charset="UTF-8">
  <title>Page Title</title>
</head>
<body></body>

Contains all the content that is visible on the webpage.

<body>
  <h1>This is visible content</h1>
  <p>Everything you see on the webpage goes here.</p>
</body>

Text Formatting Tags

Headings: <h1> to <h6>

HTML provides six levels of headings, with <h1> being the most important and <h6> the least important.

<h1>Main Heading</h1>
<h2>Subheading</h2>
<h3>Smaller Subheading</h3>

Paragraphs: <p></p>

Used to define paragraphs of text.

<p>This is a paragraph of text. HTML will automatically wrap the text and adjust it to the screen size.</p>

Line Break: <br>

Inserts a single line break. This is an empty element (no closing tag required).

<p>This text will be on the first line.<br>This text will be on the second line.</p>

Horizontal Rule: <hr>

Creates a horizontal line, useful for separating content sections. This is also an empty element.

<p>Section 1 content</p>
<hr>
<p>Section 2 content</p>

Text Formatting:

 

<strong></strong> or <b></b> - Bold text
<em></em> or <i></i> - Italic text
<u></u> - Underlined text
<mark></mark> - Highlighted text
<small></small> - Smaller text

 

<p>This is <strong>bold</strong> and this is <em>italic</em>.</p>
<p>This is <u>underlined</u> and this is <mark>highlighted</mark>.</p>

List Tags

Ordered Lists: <ol></ol>

Creates a numbered list.

<ol>
  <li>First item</li>
  <li>Second item</li>
  <li>Third item</li>
</ol>

This displays as:

  1. First item
  2. Second item
  3. Third item

Unordered Lists: <ul></ul>

Creates a bulleted list.

<ul>
  <li>Apple</li>
  <li>Banana</li>
  <li>Orange</li>
</ul>

This displays as:

  • Apple
  • Banana
  • Orange

Definition Lists: <dl></dl>

Used for defining terms.

<dl>
  <dt>HTML</dt>
  <dd>Hypertext Markup Language</dd>
  <dt>CSS</dt>
  <dd>Cascading Style Sheets</dd>
</dl>

Link Tags

Anchor: <a></a>

Creates hyperlinks to other pages or resources.

<a href="https://www.example.com">Visit Example.com</a>
You can also link to other pages within your site:
<a href="contact.html">Contact Us</a>
Or create bookmarks within a page:
<a href="#section2">Go to Section 2</a>

<!-- Later in the document -->
<h2 id="section2">Section 2</h2>

Image Tags

<img>

Embeds images in your webpage.

<img src="image.jpg" alt="Description of the image">

The src attribute specifies the path to the image file, while the alt attribute provides alternative text for screen readers and displays if the image fails to load.

Table Tags

<table></table>

Creates a table structure.

<table border="1">
  <tr>
    <th>Name</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>John</td>
    <td>25</td>
  </tr>
  <tr>
    <td>Jane</td>
    <td>28</td>
  </tr>
</table>
This creates a simple table with headers and data cells.

Form Tags

<form></form>

Creates a form for user input.

<form action="submit.php" method="post">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name"><br><br>
  
  <label for="email">Email:</label>
  <input type="email" id="email" name="email"><br><br>
  
  <input type="submit" value="Submit">
</form>
Common form elements include:
  • <input> - Various input types like text, password, radio, checkbox
  • <textarea> - Multi-line text input
  • <select> and <option> - Dropdown lists
  • <button> - Clickable button

Semantic HTML5 Tags

HTML5 introduced several semantic elements that provide meaning to the structure of web pages:

<header></header>

Represents introductory content or a set of navigational links.

<header>
  <h1>Website Title</h1>
  <nav>
    <ul>
      <li><a href="index.html">Home</a></li>
      <li><a href="about.html">About</a></li>
    </ul>
  </nav>
</header>
<nav></nav>

Defines a set of navigation links.

<main></main>

Specifies the main content of the document.

<article></article>

  2. Keep It Clean: Properly indent your code to make it readable.

  3. Be Consistent: Use consistent naming conventions for classes, IDs, and file names.

  4. Validate Your HTML: Use tools like the W3C Markup Validation Service to check for errors.

  5. Accessibility Matters: Always include alt text for images and use semantic HTML to help screen readers.

  6. Mobile-Friendly: Use responsive design principles to ensure your site works on all devices.

  7. Keep Learning: HTML works best when combined with CSS for styling and JavaScript for interactivity.

Next Steps After Learning Basic HTML

Once you've mastered the basics of HTML, you can expand your skills by:

  1. Learning CSS: Cascading Style Sheets allow you to style your HTML elements, making them visually appealing.
