CSS is used to style and layout web pages. It determines how HTML elements are displayed on screen, paper, or other media. Here's a basic CSS example:
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
}
h1 {
color: #333;
text-align: center;
}
JavaScript
JavaScript is a powerful programming language that adds interactivity and dynamic behavior to websites. Here's a simple JavaScript function:
