How can CSS be utilized in conjunction with PHP to improve the presentation of data output on web pages?

When using PHP to output data on web pages, CSS can be utilized to improve the presentation of that data by applying styles such as colors, fonts, spacing, and layout. This can make the data more visually appealing and easier to read for users. By combining PHP for dynamic data generation and CSS for styling, web developers can create more professional and user-friendly websites.

<?php
// PHP code to output data
$data = "Hello, World!";
echo "<div class='styled'>$data</div>";
?>
```

```css
/* CSS code to style the output data */
.styled {
  color: blue;
  font-size: 18px;
  padding: 10px;
  border: 1px solid black;
}
