What is the best practice for adding a background and graphics to a PHP file?

When adding a background and graphics to a PHP file, the best practice is to use HTML and CSS within the PHP file to define the styles for the background and graphics. This allows for separation of concerns and easier maintenance of the code. You can use inline styles or link to an external CSS file to style the background and graphics.

<!DOCTYPE html>
<html>
<head>
    <style>
        body {
            background-image: url('background.jpg');
            background-size: cover;
            background-position: center;
        }
        .graphic {
            width: 100px;
            height: 100px;
            background-image: url('graphic.jpg');
            background-size: contain;
            background-repeat: no-repeat;
        }
    </style>
</head>
<body>
    <div class="graphic"></div>
</body>
</html>
