Add a "class selection" field to content item via CCK?

Question

I have a single content type (webform) that I want to display in two or three different styles on my site. For instance, I may want to have some of the webform's CCK fields floated to the right on one webform page, and have them floated to the left on another. There will be many unique webform content items on the site, so individual CSS per-page styling would not work well, and I am looking for a point-and-click solution.

I was hoping that there would be a way for me to add a CCK field (or something similar) to the Webform content item that would allow me (or another admin user) to simply choose "style 1", "style 2", or "style 3" from a drop-down menu, and that style would be added to that Webform's page or div classes, allowing that form to be stylized according to one of three pre-created style sets.

Is this possible with an existing module? Any other ways in which I can go about accomplishing this?

Thanks!

// This code will add a class to the node based on a field in that node
function THEME_preprocess_node(&$vars) {
$node = $vars['node']; 
$output = '';

switch($node->type) {
  case 'advertisement':

  // Set class based on editor color selection; code duplicated for clarity.
  $field = field_get_items('node', $node, 'field_background_color');
  if($field) {
    $theme = field_view_value('node', $node, 'field_background_color', $field[0]);
    $term_name = $theme['#title'];
    $term_name = str_replace(' ', '-', $term_name);
    $css_name = strtolower($term_name);
    $vars['classes_array'][] = $css_name;
  }
  break;
  }
}

I found a great way to accomplish this using the Context module.

First, I added a Taxonomy CCK field to the Webform content type, and then...

In Admin /Structure /Context, in a context, add a "Taxonomy" Condition of tag, "Theater," and set a "Theme HTML" Reaction.

This adds whatever class you specify to the body class for the webform page, depending on whether you select one of the qualifying taxonomy terms from the Taxonomy CCK field when editing that Webform.
