Generate a bxSlider from a Custom Post Type

custom-cpt-slider.php

<div class="bx-wrapper">
  <ul class="bxslider">    
      <?php 	    
        $slider = new WP_Query(array( 'post_type' => 'homepage_slider' ) );		
	if( $slider->have_posts() ) : 
	  while($slider->have_posts()) : 
	  $slider->the_post();
			
	  $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full' ); ?>
    	  <li class="featured-image" style="background-image: url('<?php echo $thumb['0'];?>')">
      	        <div class="slide-wrapper">
		    <div class="slide-inner">
        	         <?php the_content() ?>
                    </div>
                </div>
          </li>
      <?php 
        endwhile; 
	endif; 
	wp_reset_postdata(); 
       ?>
    </ul><!-- /.bxslider -->
</div><!-- /.bx-wrapper -->

Not sure about the divs - maybe use span instead?
