I have created a module to add css to a survey, and this works well as most survey elements have a class associated with that survey.  The problem is that there are specific questions I would like to add more custom css to.  At first glance I thought this looked trivial as each of the survey questions has an id.  Then I realized the id started with a number which made it not accessible.  I believe a long term solution for this would be to change the id from 2_13_57 (which would be survey id 2, page id 13, question id 57) to survey_2_13_57.  I may end up changing this in the module directly but if anyone has a better short term solution I am open to suggestions.
