What best practices should be followed when designing PHP code that interacts with HTML and CSS for cross-browser compatibility?

When designing PHP code that interacts with HTML and CSS for cross-browser compatibility, it is important to use CSS frameworks like Bootstrap or Flexbox to ensure consistent styling across different browsers. Additionally, always validate your HTML code using a tool like W3C Validator to catch any errors that may cause issues in certain browsers. Lastly, consider using PHP libraries like PHP Simple HTML DOM Parser to manipulate HTML elements dynamically for better compatibility. 

// Example of using PHP Simple HTML DOM Parser to manipulate HTML elements dynamically

include('simple_html_dom.php');

$html = file_get_html('http://www.example.com');

// Find all <a> tags with a specific class
foreach($html->find('a[class=myclass]') as $element) {
    // Add a new class to the found elements
    $element->class .= ' newclass';
}

// Output the modified HTML
echo $html;
