Editor doesn't change the form width

Hello,

I'm dealing with a problem for hours and I cant't find the solution/problem: I want to enlarge the width of my form. But the only elements that are changing are the logo region and the jotform footer. Can you tell me what I'm doing wrong?

Thank you for your help!

I have checked the form and it seems like it has a max width configured, you can overwrite that with this code: 

.form-all {

    max-width: none !important;

}

This guide will help you injecting the code: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes 

I hope this helps.
