Can you resize a form to be smaller

If I want the form to be a certain size can I use css code and a div tag to control the size?

Example 300 px wide by 500 px high

If you are trying to re-size a form in order to make mobile responsive, let me share with you that we have a Mobile Responsive Widget that can help you accomplish that. 

You can inject custom CSS codes in your form, so try injecting this code:

.form-all{

height: 300px;

width: 500px;

}

Also you can  adjust the width of the form from the form builder:

And reduce the vertical space between fields, since the form´s height auto-adjust itself. Let us know if you have more questions, we will be glad to assist you.
