我想为WordPress安装的主页创建自定义缩略图对话。

这就是我想要实现的目标：

这是上图的引导代码：

<div class="row">
    <div class="col-sm-6 col-md-4">
        <div class="thumbnail">
            <img src="..." alt="...">
            <div class="caption">
                <h3>Thumbnail label</h3>
                <p>...</p>
                <p>
                    <a href="#" class="btn btn-primary" role="button">Button</a>
                    <a href="#" class="btn btn-default" role="button">Button</a>
                </p>
            </div>
        </div>
    </div>
</div>

因此，到目前为止，我有下面的代码，我不能在一行中包含内容。

<div class="row">   
    <div class="col-sm-6 col-md-4">
        <?php // theloop
        if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>        

<?php// Define our WP Query Parameters ?>
<?php $the_query = new WP_Query( \'posts_per_page=3\' ); ?>

<?php// Start our WP Query ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>


<div class="thumbnail"><?php the_post_thumbnail(array(100, 100)); ?>
<div class="caption">            
<?php// Display the Post Title with Hyperlink?>
<h3><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h3>


<?php// Repeat the process and reset once it hits the limit
</div>    
</div>
</div>   
<?php
endwhile;
wp_reset_postdata();
?>

下面的屏幕截图反映了我当前代码的结果（不可取）：

我怎样才能做到？

        <div class="row">   
          <h4>Noticias Recentes</h4>
          <?php // theloop
        if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>


<?php// Define our WP Query Parameters ?>
<?php $the_query = new WP_Query( \'posts_per_page=3\' ); ?>

<?php// Start our WP Query ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>

      <div class="col-sm-6 col-md-4">

<div class="thumbnail"><?php the_post_thumbnail(array(100, 100)); ?>
<div class="caption">            
<?php// Display the Post Title with Hyperlink?>
<h3><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h3>



<!--// Repeat the process and reset once it hits the limit-->
</div>    
</div>    
</div>  
<?php
endwhile;
wp_reset_postdata();
?>
