font-family: Arial, sans-serif;
background-color: #f2f2f2;
}
h1 {
color: #333;
}
p {
font-size: 16px;
line-height: 1.5;
}
JavaScript
JavaScript is a versatile programming language that adds interactivity and dynamic behavior to web pages. It enables developers to create interactive forms, validate user input, manipulate the DOM (Document Object Model), and make asynchronous requests to web servers.
// Example JavaScript
function greetUser() {
var userName = prompt(“What’s your name?”);
alert(“Hello, ” + userName + “!”);
}
