Answer In a typical web development scenario using HTML, CSS, and JavaScript, it's important to understand that C (the programming language) is not directly involved in manipulating the DOM (Document Object Model) or handling client-side interactions. C is a server-side language, and web development tasks like changing CSS class names are usually performed on the client side using JavaScript.
If you are working in a context where C is involved in server-side processing and you need to dynamically generate HTML with different CSS classes, you might use C to generate HTML code dynamically or apply different classes based on certain conditions. However, the actual manipulation of the DOM and client-side behavior is usually handled by JavaScript.
Here's a very basic example of how you might dynamically set a CSS class using JavaScript:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Change CSS Class</title>
<style>
.originalClass {
color: blue;
}
.newClass {
color: red;
}
</style>
</head>
<body>
<p id="myParagraph" class="originalClass">This is a paragraph.</p>
<script>
// Get the element by ID
var myParagraph = document.getElementById("myParagraph");
// Change the class dynamically
myParagraph.className = "newClass";
</script>
</body>
</html>
In this example, the JavaScript code selects an HTML element with the ID "myParagraph" and dynamically changes its CSS class from "originalClass" to "newClass."
If you're working in a specific web framework or context that involves server-side processing with C, the details may vary. Please provide more context if you have a specific environment or framework in mind.
