    How about on another browser? Can you give it a try? Your screenshot is in Firefox, right? How about its version? Please check that as well, and make sure you have the latest version. 

    Also, please check your browser console for related errors. The following guides should help you navigate the console area:



    Please take a screenshot and upload that on this thread. You have to access this thread to upload the screenshot (guide: https://www.jotform.com/answers/277033).

    In the video it shows you were modifying the form width to about 20px... that was the reason form appear like that.

    I also noticed that there were error in the CSS codes used on the form. It could be causing the glitch as well. You can try removing first the CSS codes or correct the mistakes and check again.

    I cloned your form so that I could test using my Form Builder, but I could not reproduce the issue. 

    I corrected the CSS codes used on the form also.


    .supernova, .jotform-form, .form-all {

        background-color : transparent !important;


    .form-required {

        float : left;

        margin-left : -25px;

        position : relative;

        top : 10px;


    .form-line.jf-required {

        padding : 1px 21px 1px 10px;


        .form-number-input.form-textbox {

        width : 130px;


        button#input_24 {

        border : none !important;

        margin-top : 35px !important;


    .form-textbox {

        line-height : 20px;



    Try replacing your form with this as well. Let us know how it goes.
