What is Web Development?

Web development is the process of creating websites and applications accessible over the internet. It is based on three main technologies: HTML for structure, CSS for design, and JavaScript for interactivity.

Main Web Development Technologies

  • HTML (HyperText Markup Language): Defines the structure of a web page using tags.
  • CSS (Cascading Style Sheets): Allows you to style and design HTML elements.
  • JavaScript: Adds interactivity and dynamism to web pages.

Example of a Basic Web Page

This code shows how to combine HTML, CSS, and JavaScript into a simple web page:

<!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
    <style>
        body {
            font-family: Arial, sans-serif;
            text-align: center;
        }
        button {
            padding: 10px;
            background-color: blue;
            color: white;
            border: none;
            cursor: pointer;
        }
    </style>
</head>
<body>
    <h1>Hello, World!</h1>
    <p>This is a basic example of a web page with HTML, CSS, and JavaScript.</p>
    <button onclick="saludar()">Click here</button>

    <script>
        function saludar() {
            alert("Welcome to web development!");
        }
    </script>
</body>
</html>

This example shows how to structure a web page with HTML, style it with CSS, and add interaction with JavaScript.

Conclusion

Mastering HTML, CSS, and JavaScript is essential for any web developer. These technologies form the foundation of the modern web and enable you to create interactive and engaging user experiences.
