I need a truly transparent form

I have built my form and it functions great, but I am embedding it into my website and cannot get it to have a transparent background. Even going into the design portion of the website, I am able to see what I believe should make my background transparent in the color settings. But when I select no background color, and the icon shows me the checkerboard grid, I still have a white background when I publish. I want to see all the way through to my HTML background-image. How can I do that?

I checked your form and I can see that the form has the same background as your webpage. 

I assume you have resolved the issue and was able to make the background transparent? If you have any other concerns, feel free to contact us again.
