How can I remove the extra white space underneath the form?

I'm not sure how to remove the unnecessary space after the form design i've created. Looking for help on this. See screenshot attached. 

To adjust the spacing at the bottom of the form, add the following code:

.form-all {

    margin-bottom : -40px;

    padding-bottom : 0px;

}

Adjust the values to suit your form. 

If that does not allow for properly adjusting the form, let us know what form you are working with and if it is embedded to a webpage, the URL of the page the form is added to.
