 * Hi everyone
 * I am working on a site want to have three random column widths. I found an example
   that hows me how to generate the random number for the class
 * `<a href="<?php the_permalink(); ?>" class="box col<?php echo rand(2,4); ?>">...
   </a>`
 * but in my theme I am using _post\_class()_ so I am not sure how to add the echo
   rand statement.
 *     ```
       <article id="post-<?php the_ID(); ?>" <?php post_class('box col'); ?>>
       ...
       </article>
       ```
   
 * I am still learning all this and have tried how I thought it should be concatenated
   but none of them worked. If someone could point me in a direction or tell me 
   a better way it would be greatly appreciated
 * Thx

 * Try…
 *     ```
       <?php $num=rand(2,4); ?>
       <article id="post-<?php the_ID(); ?>" <?php post_class('box col'.$num); ?>>
       ...
       </article>
       ```
   
 * This isn’t tested, but I don’t see why it wouldn’t work.
