Appliqué

Appliqué aspires to make form elements such as selects, radio buttons and check boxes easy and fun to style.

The module will replace all form elements with an HTML/jQuery equivalent on a per-form basis. In the module settings, a list of available forms on the site will be populated and the user can choose which forms are affected by the module (by default, no admin-side forms are affected). The module will come with only the CSS necessary for form elements to function, and different form "skins" can be contributed, uploaded and plugged into the module.

The module is very much a work in progress. Checkout https://drupal_form_styler.assembla.com/wiki/show/drupal_applique for details and updates on progress.

Update:

The Uniform module does much of what I planned to do with Appliqué, and it was completed first :)
