I am unable to set my form background as transparent

I read the other comments and changed the background to transparent, but it is still showing up white.

I took a look at your website and I see the white background is still there.

To remove it, please add the following CSS code to your jotform:

html.supernova {
    background: transparent none;
}

You can do that by following the steps here: Inject Custom CSS Codes

Please add the code at the bottom of all the other code that you have in that field.
