How can I add more space on the right side of my form?

This is my current form alignment...

I would like to keep everything aligned left, but add more empty space on the left side of the form so that the overall form is centered with the JotForm ad on the bottom.

How do I do this?

You can do this with some CSS codes. I cloned your form and tried it. So, if you can paste the code following, you can fix it. 

.form-line {

    margin-left:40px;

}

By changing the margin value, you can arrange the place. To do this, follow the steps below.

1- Go to Form Builder>>Form Designer

2- Then, click on the CSS tab and paste the code.

If you have any further questions, please feel free to let us know.

it worked! thanks!
