Understanding Web Development
Web development is the process of creating websites and web applications that users can access through their browsers. It involves two main components: front-end development and back-end development. The front-end is what users see and interact with, while the back-end handles the behind-the-scenes operations, such as storing data and processing user requests.
Key Technologies in Web DevelopmentHTML (Hypertext Markup Language): HTML is the building block of every web page. It structures content using elements like headings, paragraphs, links, images, and more. Here's a simple example of HTML code:
html<!DOCTYPE html>
<html>
<head>
<title>My First Web Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a basic example of an HTML page.</p>
</body>
</html>
- CSS (Cascading Style Sheets): CSS is used to style HTML elements and make web pages visually appealing. It controls attributes like colors, fonts, spacing, and layout. Here's a snippet of CSS code:
cssbody {
font-family: Arial, sans-serif;
background-color: #f2f2f2;
}
h1 {
color: #333;
}
Here's a simple JavaScript example:
Putting It All Together
Let's combine these technologies to create a basic web page. Save the following code as "index.html" and open it in your web browser:
javascriptfunction greet() {
var name = prompt("What's your name?");
alert("Hello, " + name + "!");
}
Putting It All Together
Let's combine these technologies to create a basic web page. Save the following code as "index.html" and open it in your web browser:
html<!DOCTYPE html>
<html>
<head>
<title>My First Web Page</title>
<link rel="stylesheet" type="text/css" href="styles.css">
<script src="script.js"></script>
</head>
<body>
<h1>Hello, Web Developers!</h1>
<p>This is an example of a simple web page.</p>
<button onclick="greet()">Say Hello</button>
</body>
</html>
In this example, we've linked an external CSS file ("styles.css") for styling and an external JavaScript file ("script.js") for interactivity. The JavaScript function "greet()" prompts the user for their name and displays a greeting.
