CSSTricks has created a Website Change Request Form, in order to show off some fancy form styling and advanced form functionality. The form is fully functional, submission can only happen when the required fields are filled out properly. Submission is handled via AJAX, no page refresh needed.

jqTransform is used to help with the styling of the form elements. It completely replaces radio buttons and check boxes with custom graphics, and wraps textareas and text-based inputs in nice styling as well. The submission of all the form elements is SERIALIZED, via jQuery Form Plugin, so adding and changing form elements is easy.

Requirements: jQuery Framework
