jquery validation plugin textarea

Usi开发者_开发技巧ng the jquery validation plugin in the event of a textarea failing validation - required - it is not being highlighted. Looking for suggestions on how to make this happen.

in the CSS for the plugin, there's only:

input.error { border: 1px dotted red; }

it should be

input.error, textarea.error { border: 1px dotted red; }

The problem actually happens in the Demo website for the plugin.
