You can apply custom CSS codes to a form by only copying them to your form's source code.
There are several ways to do that:

2. Another way, just download the source code of your form by using THIS tutorial, then you can edit it manually.

The reason for using our own css was that the background is not a solid colour rather its transparent

Just use THIS tutorial to make your form transparent.
Just give it a try and let us know about last situation.
