Thank you page border

Hi, I have embeded a form on my website and have just noticed that when the Thank you message loads it has a border around it which i do not want. Is there a way to get rid of this border?

Could you kindly provide us with a link to your page or the embedded form so that we may be able to advise on how to correct the border issue on your form.

kindly add the following CSS to you form using the designer.

#stage.form-all
{
    box-shadow:none !important;
}
