css - Firefox 4 Required input form RED border/outline -

I have recently developed an HTML5 jQuery plugin and I have trouble removing the red border on the required field in FF4 beta Is happening / P>

I noticed that FF applies this threshold / limit to the required fields and when the value is set, it removes it. The problem is that I am using the value attribute to emulate the placeholder ARR in the old browser. Therefore, I do not need to display the red line with all the inputs with this feature.

You can see the problem in the demo page of

Available to you in CSS There are some new pseudo selectors for some new HTML forms. You are probably looking for : invalid following all of the following:

• : invalid CSS pseudo-class automatically Elements which have failed to validate the type of content input according to the settings.

• If there is no one or more form field, then : - Moz-submit-invalid is applied on the submission button on the pseudo-square form field, valid.

• : Required Pseudo-class is now automatically applied to fields that specify the necessary attributes; : Optional Pseudo range is applied to all other areas.

• : - The mosaic-placeholder has been added to the pseudo-class so that you can style the placeholder text to the form placeholder.

  The pseudo selector lets you specify the form of an element when Goku assumes that the element should be the focus of the focus.
