What are the best practices for structuring PHP and HTML code to avoid styling issues like link colors displaying incorrectly?

Styling issues like link colors displaying incorrectly can be avoided by ensuring that CSS styles are properly applied to HTML elements. One way to achieve this is by using PHP to dynamically generate HTML code with inline styles or by including CSS files in the head section of the HTML document.

<!DOCTYPE html>
<html>
<head>
    <style>
        a {
            color: blue; /* Set link color to blue */
            text-decoration: none; /* Remove underline */
        }
    </style>
</head>
<body>
    <a href="#">Example Link</a>
</body>
</html>
