title: How to add a class to a WooCommerce product within the product loop
body: <p>I would like to add multiple bootstrap col classes to this line of code inside the product loop but I have no idea. </p>
  
  <pre><code>&lt;li&gt;&lt;?php wc_product_class(); ?&gt;&lt;/li&gt;
  </code></pre>
  
  <p>Can I somehow push my classed into this bit of php and still keep the product applied?</p>
