A Light weight, small framework for beautiful forms: Ideal Forms
Ideal Forms is a lightweight framework, built on the top of jQuery, for creating good looking and user-friendly forms.
It converts standard <input> elements into ones with rounded corners having an attractive focus effect. And, radio + checkbox elements are completely customized.
No images are used, they requires minimal HTML syntax and can be completely styled with CSS (comes with 3 themes).
The framework is unobtrusive and degrades gracefully with JavaScript disabled.

Requirements: jQuery
Compatibility: IE 7+, Firefox 3+, Chrome 3+, Safari 3.1+ and Opera 11+
