Newbie: Using css to style fields in a content type I created a content type using html elements as fields and groups. The content type configuration page allows me to add classes (and id attributes) to the elements; however, they don't show up in the generated html when I view page source in a browser.  

I gather from Add a CSS class to field in content type that I must modify php functions to actually include the classes in the output css; however, I'm a newbie and don't really understand the post.  It refers to a blog post which is no longer available.

I can't find the function ( theme_field ) in any of my template.php files.  Can someone help clarify this for me.  How can I get my own classes into drupal output.

Thanks.
There is a much easier way, but is still complicated if you're a newbie. Install the Display Suite module and enable Display Suite &amp; Display Suite UI

Go to Structure -> Display Suite -> CSS classes. Add as many CSS classes for fields as necessary. Go to Structure -> Content types -> [xxx] -> Manage Display and you should be able to put the classes you have defined against each of the fields.
