What are the best practices for using percentage-based measurements in CSS when working with PHP?

When working with PHP and CSS, it is important to ensure that percentage-based measurements in CSS are calculated correctly based on the content being generated dynamically by PHP. To achieve this, it is recommended to use PHP to output the dynamic content within a container element, and then apply percentage-based measurements to the container element in the CSS. This way, the layout will adjust dynamically based on the content generated by PHP.

<?php
// PHP code to generate dynamic content
$dynamicContent = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";

// Output the dynamic content within a container element
echo '<div class="container">' . $dynamicContent . '</div>';
?>
```

```css
/* CSS code to apply percentage-based measurements */
.container {
  width: 50%;
  margin: 0 auto;
}
