To make a hosted Web form transparent, just add an html snippet, and add the following code:

<style>
  #mainContent .background, #mainContent .body {
    background-color: transparent;
  }
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
  jQuery(document).ready(
    function(){
      jQuery('#mainContent td.body, table.bodyContainer').removeAttr('bgcolor');
    }
  );
</script>
