How to eliminate the dark grey (transparent) background?

I hope this is simple...I would like to eliminate the grey transparent background that is like a frame around my question fields, so that only the light green color is showing through. Is that possible? I am planning to use this form as an iframe embed, and I want the background to be a brighter green. The grey is messing me up. Thank you so much!

Hi,

Adding this CSS to your form should remove the grey background:

.form-all {
    background-color : transparent !important;
}

You can change the color from transparent to whatever you would like in order to adjust the frame background.  Leaving it as transparent show the light green background from the rest of the page.  Here is my test form with the code added:
