How to remove the line above the send button and the scroll bar

How to remove the line above the send button

Even all of the form fitting, it still shows a vertical scroll bar on the right. How do I remove it with CSS code? Or maybe remove the empty space under the from. And also I want to remove the line under the send button.

For the horizontal bar on top, you can remove it by injecting this CSS code into your form:

.form-pagebreak {
   border-top: 0 !important;
}

You can follow this guide to know how to inject CSS codes into your form: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes 

For your question about the scroll bars, in order for us to be able to understand this further, can you share with us on how you are able to see this scroll bar, like are you viewing the form while it being embedded on a page or such that you are using a specific browser?

We'll look forward to your response.

Thanks.

Yes, the form is embedded via iframe in my site. The vertical bar appears on all browsrs.

The horizontal bar only disappears when I extend the iframe area to more than double the forms size.. so it's like there's empty space there somehow (image below) So what do we do?
