Inline CSS with IDs

Thank you for the tpl file but to have it easier to style out of the box could you remove the inline styles with the hard-coded ID #selectors and just use some base classes that can be overwritten in the theme?

Referring to this:

<style type="text/css">
  #pcp-wrapper-<?php print $entity_type . '-' . $bundle; ?> .pcp-percent-bar-wrapper {width: 100%; border: 1px solid #000; padding: 1px;}
  #pcp-wrapper-<?php print $entity_type . '-' . $bundle; ?> .pcp-percent-bar { width: <?php print $current_percent; ?>%; height: 10px; background-color: #777;}
</style>
