Why my form does not keep the background transparent while embedded?

Also, the JotForm does not allow transparent, if we select transparent it displays in white on our webpage, that had not happened previously either.

I have tested the background transparent property and I can see it works on my end. 

I have set the background to transparent on for the form and iFrame page as well:

When I embedded my form I could see the background was transparent: 

Could you please set the background to transparent through the form designer tool? 

Please, do let us know how it goes.
