    Dear Jotform support staff

    Good evening.

    I've been a very satisfied user of your product since a couple of years now. Among several forms that have been successfully put to use up to now there is one that is accessed by clicking a button starting the form filling process inside a lightbox. It´s composed of three pages, the first two of which comprehend a checklist of procedures and are working as expected.

    However, I recently noticed the third section is presenting a malfunctioning when viewed with Google Chrome. It contains headers,  some text and a number of text boxes to be filled. At that point of the form, the screen inside the lightbox shows itself trembling from right to left in an uncontrolled fashion, as if the elements were struggling to fit or accomodate in the width of the inner screen. It doesn't respond to any commands one would try to do to stop its motion.

    This problem hasn't been observed in Mozilla and even in Chrome everything was working fine until last week. I would like to ask for your help with this issue, please.

    The form is hosted at:

    Thank you very much!

    I checked your form on Chrome and I can confirm that the form is constantly changing its width and height, causing the fields on the form to move erratically. You can resolve this issue by injecting the CSS code below. This code sets a fixed width on the form to prevent it from constantly changing.


        width: 690px;
