    Hi Masa,

    You can use this CSS code, simply inject this to your form. Guide: How to Inject Custom CSS Codes to your Form

    You will be able to see the opacity when you embed your form. Example:  http://formdemos.awardspace.biz/formTemplate15.html

    To learn more about opacity background, check this guide: http://www.jotform.me/help/122-How-to-Adjust-the-Opacity-of-a-Form-s-Background

    Thanks for your quick reply. 


    There are two more things I would like to know.

    1. CSS code for roundred corner for the back ground (using the semi transparent) 


    2. Is it possible to have a fluid background? I want my back ground to fill the screen, no matter the size of the screen. 

    Many thanks!

    You can inject this code for rounded corner 

    .form-all {
    border-radius: 15px 15px 15px 15px !important;}


    As for your 2nd question, I'm not quite sure about it but you can try setting the height and width of the form to 100%. Thanks!
