How can CSS be leveraged to improve the styling and presentation of PHP-generated content in a forum?

To improve the styling and presentation of PHP-generated content in a forum, CSS can be leveraged to apply styles such as colors, fonts, margins, and padding. By separating the content generation logic in PHP from the presentation logic in CSS, it allows for easier maintenance and customization of the forum's appearance.

<?php
// PHP code to generate forum content
$forumContent = "<div class='forum-post'>
                    <h2>Title of the post</h2>
                    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
                  </div>";
echo $forumContent;
?>
```

```css
/* CSS code to style forum post */
.forum-post {
  background-color: #f9f9f9;
  border: 1px solid #ccc;
  padding: 10px;
  margin-bottom: 10px;
}

.forum-post h2 {
  color: #333;
}

.forum-post p {
  font-size: 14px;
}
