What are the best practices for styling text output in PHP to ensure compatibility with modern browsers and CSS standards?

When styling text output in PHP to ensure compatibility with modern browsers and CSS standards, it is best to use inline styles or classes with CSS. This allows for separation of content and presentation, making it easier to maintain and update styles. Additionally, using CSS properties like font-family, font-size, color, and text-align will help achieve a consistent and visually appealing design.
