php load database side-by-side

<?php
        try {

            $stmt = $db->query('SELECT postID, postTitle, postDesc, postDate FROM blog_posts ORDER BY postID DESC');
            while($row = $stmt->fetch()){

                echo '<div>';
                    echo '<h1><a href="viewpost.php?id='.$row['postID'].'">'.$row['postTitle'].'</a></h1>';
                    echo '<p>Posted on '.date('jS M Y H:i:s', strtotime($row['postDate'])).'</p>';
                    echo '<p>'.$row['postDesc'].'</p>';             
                    echo '<p><a href="viewpost.php?id='.$row['postID'].'">Read More</a></p>';               
                echo '</div>';

            }

        } catch(PDOException $e) {
            echo $e->getMessage();
        }
    ?>

This code loads the data by rows. I need to load the data side by side.. Any quick helps...
