打印师3连续（从左到右）

Question

以下代码结果从左到右显示。在打印时，它逐一下降。打印地址。如何连续从左到右3打印？

<section class="contact-page-section">
      <div class="container">
                <div class="row">
    <?php

                $query = "SELECT * FROM sub";

                $num_results_per_page = 4;
                $num_page_links_per_page = 5;

$result = mysql_query($query);
$row = mysql_fetch_array($result);
pagination($query, $num_results_per_page, $num_page_links_per_page, $pg_param);

if($pg_error == '')
{
if(mysql_num_rows($pg_result) > 0)
    {
    while($data = mysql_fetch_assoc($pg_result))
        {
        echo "<div class=\"col-md-3 col-sm-6\">
                        <div class=\"shop-item-small bg-alfa\">

                        </div>
                    </div>";
        }


echo "<div class=\"errormsg\">$pagination_output</div>"; 
}
else
{
echo "<p>No subscriptions to display</p>";
}
}
else{
echo $pg_error; //display any errors, you can remove this if you want}?>
