How to change width of banner image?

Looks like a bug. 

We can change width of the banner to fix this problem.

Please follow these steps below in order to add css codes to your form:

1- Please go to form builder page.

2- Please click on the circled layout button that's on the top right corner.

3- Please click on the CSS section.

4- Please add CSS code is shown below:

#cid_8 img {
  width: 100% !important;
}

5- Please make sure to click on the save button.

I created an example form for this process:

Thx, that fixed it!

But, is there a way to center it, without changing the width?

thx

My apologies, but I am not sure if I understand the requirements correctly. Would you like to get the layout similar to screenshot below?

In this case, image exceeds the margins of a form, so maybe it would be better to crop the image if you would like to zoom it in? 

Please let us know what would work better for you and we will gladly assist.
