How to handle jquery validate error messages?

Here's the case: I have two inputs, the two are validated with the validate, one I need to show the error msg and change the border color, the other just need to change the color of the boar, without error msg . Is it possible to do that? For even not quoting the input in messages the label appears (blank but appears), and ends with my whole layout. I would like to help someone if possible. Thank you.
