Introduction to Web Development

HTML (Hypertext Markup Language) is the standard language used to create web pages. Understanding its structure is essential for any web developer.

Key Components of HTML:

<h1>This is a main heading</h1>
<h2>This is a subheading</h2>

Paragraphs: Use <p> tags to define blocks of text.

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

Links: Use <a> tags to create hyperlinks.

<a href="https://www.example.com">This is a link</a>

Images: Use <img> tags to include images.

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

HTML Basics: Structure of a Web Page (Headings, Paragraphs, Links, Images)

Let’s create a simple HTML page. Follow these steps:

Open a Text Editor: Use any text editor like Notepad, VSCode, or Sublime Text.
Create a New File: Save it as index.html.

Basic HTML Template:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
</head>
<body>
    <h1>Welcome to My First Web Page</h1>
    <p>This is a paragraph of text that provides some information.</p>
    <a href="https://www.example.com">Click here to visit an example site</a>
    <img src="image.jpg" alt="A sample image">
</body>
</html>

Understanding the Box Model

The box model is a fundamental concept in CSS that describes how elements are structured and styled on a webpage. Each HTML element is considered a box, which consists of the following:

Content: The actual content of the box, such as text or images.
Padding: Space between the content and the border of the box.
Border: A line that surrounds the padding (if any).
Margin: Space outside the border that separates the box from other elements.
```
| Margin |
| Border |
| Padding |
| Content |
```

Hands-on: Creating Your First HTML Page

CSS (Cascading Style Sheets) is used to style HTML elements. You can apply styles in different ways:

1. Inline Styles: Directly within the HTML element

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
    <style>
        body {
            background-color: #f0f0f0;
            font-family: Arial, sans-serif;
            color: #333;
        }
        h1 {
            color: darkblue;
            text-align: center;
        }
        p {
            font-size: 18px;
            text-align: justify;
        }
        a {
            color: green;
            text-decoration: none;
        }
        a:hover {
            text-decoration: underline;
        }
    </style>
</head>
<body>
    <h1>Welcome to My First Web Page</h1>
    <p>This is a paragraph of text that provides some information.</p>
    <a href="https://www.example.com">Click here to visit an example site</a>
    <img src="image.jpg" alt="A sample image">
</body>
</html>

Styling with CSS: Inline Styles, Internal Stylesheets

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
    <style>
        body {
            background-color: #f0f0f0;
            font-family: Arial, sans-serif;
            color: #333;
        }
        h1 {
            color: darkblue;
            text-align: center;
        }
        p {
            font-size: 18px;
            text-align: justify;
        }
        a {
            color: green;
            text-decoration: none;
        }
        a:hover {
            text-decoration: underline;
        }
    </style>
</head>
<body>
    <h1>Welcome to My First Web Page</h1>
    <p>This is a paragraph of text that provides some information.</p>
    <a href="https://www.example.com">Click here to visit an example site</a>
    <img src="image.jpg" alt="A sample image">
</body>
</html>

Basic Styling with CSS: Colors, Fonts, and Text Alignments

You can set colors using color

body {
    font-family: Arial, sans-serif;
    font-size: 16px;
}

h1 {
    color: red; /* Color name */
}
p {
    color: #00ff00; /* Hex code */
}

Fonts:

You can change the font family, size, and style.

Text Alignment:
You can align text using the text-align property.

Text Alignment:

You can align text using the text-align property.

h1 {
    text-align: center;
}

Hands-on: Applying Basic CSS to Your HTML Page

Let’s apply CSS to the HTML page you created earlier.

Update your `index.html` to include an internal stylesheet:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
    <style>
        body {
            background-color: #f0f0f0;
            font-family: Arial, sans-serif;
            color: #333;
        }
        h1 {
            color: darkblue;
            text-align: center;
        }
        p {
            font-size: 18px;
            text-align: justify;
        }
        a {
            color: green;
            text-decoration: none;
        }
        a:hover {
            text-decoration: underline;
        }
    </style>
</head>
<body>
    <h1>Welcome to My First Web Page</h1>
    <p>This is a paragraph of text that provides some information.</p>
    <a href="https://www.example.com">Click here to visit an example site</a>
    <img src="image.jpg" alt="A sample image">
</body>
</html>

Final Steps:
