When it comes to forms, every browser displays inputs, select drop downs and buttons differently. You can style certain elements using CSS but things like radio buttons and checkboxes are determined by the browser. Luckily, there are some cool jQuery plugins available that help you add a little bit more style to your forms.

Here are a list of jQuery plugins that can help get your forms looking a bit more impressive:

jqTransform


jqTransform allows you to skin form elements with color changes on both mouse rollover and mouse click event.

Example:

CRIR


CRIR styles only radio buttons and checkboxes. It does a cool job of it but you will still need to use CSS to style other elements of your form.
