Need to call $customStyle from 'html.user'

Hello,

I would like load this part

style="<?php echo $customStyle;?>"

from /administrator/components/com_easysocial/themes/default/html/html.user.php

I think I need of this:

<?php echo $this->html('html.user', $user); ?>

My aim is getting the background label for each user category and loading this background label behind the user avatar for getting a kind of badges color around the user avatar depending of his own user category

Could you help me for calling $customStyle?

Thank you for your help
