1. What is responsive design

Responsive design refers to a design method that can automatically adapt to different screen sizes. As people increasingly use mobile phones and tablets to access websites, responsive design has become an important skill in modern web development.

Create HTML skeleton

Before creating a responsive page, you need to create an HTML skeleton. Here we can use PHP to dynamically generate HTML tags. The following code demonstrates how to generate an HTML skeleton using PHP.

<!DOCTYPE html>
<html>
    <head>
        <title><?php echo "Page Title"; ?></title>
        <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
    </head>
    <body>
        <?php echo "Hello, world"; ?>
        <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
