What role does proper HTML syntax and structure play in ensuring consistent display of PHP-generated content across browsers?

Proper HTML syntax and structure are essential for ensuring consistent display of PHP-generated content across browsers. This includes using valid HTML tags, closing tags properly, and maintaining a logical structure. Inconsistent HTML can lead to rendering issues in different browsers, causing the PHP-generated content to display incorrectly.

<!DOCTYPE html>
<html>
<head>
    <title>PHP Generated Content</title>
</head>
<body>
    <?php
        // PHP code to generate content here
    ?>
</body>
</html>
