HTML Tutorial

1. Introduction to HTML

HTML (HyperText Markup Language) is the standard language used to create and design web pages. It structures content on the web and provides a way to format text, add images, create links, and more.

2. HTML Editors

HTML editors are tools used to write and edit HTML code. They come in various forms, from simple text editors to specialized IDEs (Integrated Development Environments) with features like syntax highlighting and auto-completion.

Examples of HTML Editors:

  • Text Editors: Notepad, Sublime Text
  • IDE: Visual Studio Code, Atom

3. HTML Basics

HTML documents are composed of elements that include tags, attributes, and content. A basic HTML document includes the <!DOCTYPE html>, <html>, <head>, and <body> tags.

Basic HTML Document Example:

<!DOCTYPE html>
<html>
<head>
  <title>My First HTML Page</title>
</head>
<body>
  <h1>Hello, World!</h1>
  <p>This is a paragraph of text.</p>
</body>
</html>

4. HTML Elements

HTML elements are the building blocks of web pages. They are defined by tags and can include attributes and content.

Common HTML Elements:

  • Headings: <h1>, <h2>, etc.
  • Paragraphs: <p>
  • Links: <a>
  • Images: <img>

5. HTML Attributes

Attributes provide additional information about HTML elements. They are specified in the opening tag and usually come in name/value pairs.

Example:

<a href="https://www.example.com" target="_blank">Visit Example</a>
<img src="image.jpg" alt="Description">

6. HTML Headings

Headings are used to define the importance and hierarchy of content. HTML provides six levels of headings, from <h1> to <h6>.

Example:

<h1>Main Heading</h1>
<h2>Subheading</h2>
<h3>Sub-subheading</h3>

7. HTML Paragraphs

The <p> tag defines paragraphs in HTML. It automatically adds space before and after the content.

Example:

<p>This is a paragraph of text.</p>
<p>This is another paragraph.</p>

8. HTML Styles

CSS (Cascading Style Sheets) is used to style HTML elements. Styles can be applied inline, internally, or externally.

Inline Style Example:

<p style="color: blue;">This is a blue paragraph.</p>

Internal Style Example:

<head>
  <style>
    p {
      color: blue;
    }
  </style>
</head>

External Style Example:

<link rel="stylesheet" href="styles.css">

9. HTML Formatting

HTML provides tags to format text, such as bold, italic, and underline.

Example:

<b>Bold text</b>
<i>Italic text</i>
<u>Underlined text</u>

10. HTML Quotations

Quotations are used to include text from other sources. HTML offers several tags for this purpose.

Example:

<blockquote cite="https://www.example.com">
  This is a blockquote from an external source.
</blockquote>
<cite>Author Name</cite>

11. HTML Comments

Comments are used to add notes or explanations within the HTML code. They are not displayed in the browser.

Example:

<!-- This is a comment -->
<p>This is visible text.</p>

12. HTML Colors

Colors can be applied to text, backgrounds, borders, and more using CSS.

Example:

<p style="color: red; background-color: yellow;">This text is red with a yellow background.</p>

13. HTML CSS

CSS (Cascading Style Sheets) is used to style HTML elements. It can be included inline, internally, or externally.

Example:

<style>
  body {
    font-family: Arial, sans-serif;
  }
</style>

14. HTML Links

Links allow users to navigate between pages or to external sites. The <a> tag is used to create links.

Example:

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

15. HTML Images

Images can be added using the <img> tag. The src attribute specifies the image source, and alt provides alternative text.

Example:

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

16. HTML Favicon

A favicon is a small icon displayed in the browser tab. It is linked in the <head> section.

Example:

<link rel="icon" href="favicon.ico" type="image/x-icon">

17. HTML Page Title

The page title is displayed in the browser tab and is set using the <title> tag in the <head> section.

Example:

<head>
  <title>My Page Title</title>
</head>

18. HTML Tables

Tables are used to organize data into rows and columns. They are created using <table>, <tr>, <th>, and <td> tags.

Example:

<table>
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td>Row 1, Cell 1</td>
    <td>Row 1, Cell 2</td>
  </tr>
</table>

19. HTML Lists

Lists can be ordered (<ol>) or unordered (<ul>). List items are created with <li>.

Example:

Unordered List:

<ul>
  <li>Item 1</li>
  <li>Item 2</li>
</ul>

Ordered List:

<ol>
  <li>First</li>
  <li>Second</li>
</ol>

20. HTML Block & Inline

HTML elements are either block-level (e.g., <div>, <p>) or inline (e.g., <span>, <a>). Block-level elements take up the full width available, while inline elements take up only as much width as necessary.

Example:

<div>This is a block-level element.</div>
<span>This is an inline element.</span>

21. HTML Div

The <div> tag is used as a container for other HTML elements. It is often used for layout purposes.

Example:

<div class="container">
  <p>This is inside a div.</p>
</div>

22. HTML Classes

Classes are used to apply styles to multiple elements. They are defined with the class attribute.

Example:

<style>
  .highlight {
    background-color: yellow;
  }
</style>

<p class="highlight">This text is highlighted.</p>

23. HTML Id

The id attribute is used to uniquely identify an element. It must be unique within a document.

Example:

<p id="unique">This paragraph has a unique ID.</p>

24. HTML Iframes

The <iframe> tag is used to embed another HTML page within the current page.

Example:

<iframe src="https://www.example.com" width="600" height="400"></iframe>

25. HTML JavaScript

JavaScript can be embedded within HTML to add interactivity. It is included using the <script> tag.

Example:

<script>
  function greet() {
    alert('Hello, World!');
  }
</script>

<button onclick="greet()">Click me</button>

26. HTML File Paths

File paths specify the location of resources like images, stylesheets, and scripts. They can be absolute or relative.

Example:

<img src="images/photo.jpg" alt="Photo">
<link rel="stylesheet" href="styles/main.css">

27. HTML Head

The <head> section contains meta-information about the HTML document, such as links to stylesheets and scripts.

Example:

<head>
  <title>My Page</title>
  <meta charset="UTF-8">
  <link rel="stylesheet" href="styles.css">
</head>

28. HTML Layout

HTML layout involves structuring the content of a webpage using various HTML elements and CSS for styling.

Example:

<body>
  <header>Header Content</header>
  <nav>Navigation Links</nav>
  <main>Main Content</main>
  <footer>Footer Content</footer>
</body>

29. HTML Responsive

Responsive design ensures that web pages look good on all devices by using flexible layouts, images, and media queries.

Example:

<style>
  @media (max-width: 600px) {
    .container {
      width: 100%;
    }
  }
</style>

30. HTML Computercode

The <code> tag is used to display a single line of code, while <pre> is used for preformatted text.

Example:

<pre>
<code>
const greet = () => {
  console.log('Hello, World!');
};
</code>
</pre>

31. HTML Semantics

Semantic HTML elements clearly describe their meaning in a human- and machine-readable way. Examples include <article>, <section>, and <footer>.

Example:

<article>
  <h1>Article Title</h1>
  <p>Article content.</p>
</article>

32. HTML Style Guide

An HTML style guide ensures consistent and readable code. It covers naming conventions, indentation, and organization.

Example:

  • Use lowercase for element names and attribute names.
  • Use double quotes for attribute values.

    } else {
      alert("Geolocation is not supported by this browser.");
    }
  }

  function showPosition(position) {
    alert("Latitude: " + position.coords.latitude + 
    "\nLongitude: " + position.coords.longitude);
  }
</script>

52. HTML Drag/Drop

HTML5 provides a drag-and-drop API for moving elements.

Example:

<div id="drag1" draggable="true" ondragstart="drag(event)">Drag me</div>
<div id="drop1" ondrop="drop(event)" ondragover="allowDrop(event)">Drop here</div>

<script>
  function allowDrop(ev) {
    ev.preventDefault();
  }

  function drag(ev) {
    ev.dataTransfer.setData("text", ev.target.id);
  }

  function drop(ev) {
    ev.preventDefault();
    var data = ev.dataTransfer.getData("text");
    var draggedElement = document.getElementById(data);
    ev.target.appendChild(draggedElement);
  }
</script>

53. HTML Geolocation

HTML5's Geolocation API allows web pages to access the user's location.
