Why my form is not mobile responsive?

I assume that you're referring to this form:

I added a Mobile responsive widget to your form, please check and let us know if it works as intended now?

We'll wait for your response.

Thank you!

I have check and from my cellphone it is not working. I see half of my form (larger).

I was able to replicate the issue. Please give me more time to work on this problem. I will contact you once I have a solution. Thank you.

Thank you for waiting. Please try the following steps:

1. In Form Builder V4, click the "Form Designer" button at the right.

2. Scroll down and click the "Advanced Designer" button.

3. Go to the "Form Layout" section and enable the "Make this form responsive" option.

4. After that, go to the "CSS" tab and paste the CSS code below:

@media only screen and (max-width: 40em){
    .form-line.form-line-column {
        margin-left : 0px !important;
    }
    img.headerimg.pngfix {
        text-align : left !important;
    }
    tr {
    text-align: left !important;
    }
    .wordwrap .pspan {
    text-align: left !important;
    }
    .wordwrap .ispan {
    text-align: left !important;
    }
    #header {
    margin-left: 0px !important;
    margin-right: 0px !important;
    }
    .pagemargins {
    padding-left: 0px !important;
    padding-right: 0px !important;
    }
}

Here's the result:

Hope that helps. Thank you.
