How to remove the extra space below form ?

I have created a form in jot form. It is having just a text box (email) and a button (subscribe). Then i put that on my blog using the suggested method by jot form. The form is loading , but below the form there is some extra blank space which is not needed. Check in the screenshot given below. Tell me how i can remove that blank space ?

Hi,

You can inject CSS code to remove spaces. Here's sample code: 

.form-all {

padding-top: 0;

}

.form-line {

padding: 0 15px;

}
