    Making text area full screen on mobile

    Asked by plott on April 04, 2017 at 08:17 PM

    I have a form at:


    The text areas at the bottom look fine in preview.  However, on my phone (iPhone 6), they are confined to the first column.  How can I make them full-width?

    Thank you!

    Inject this CSS codes to your form, this should expand the textarea field on mobile.

    @media screen and (max-width:480px){

    textarea#input_28, .form-textarea {

    width: 100% !important;


    .form-textarea-limit>span {display: block;}

    Let us know how this goes. Thanks.

    Hi Elton,

    I made the assumption that the code you provided was to replace the original @media code.  I have done this, but the form still renders incorrectly on my iPhone 6.

    This is because you have enabled the "Shrink" option on the text areas, I have just checked your form and i can see that the text ares are set to shrink. All you need to do is set the shrink option as off, and they will view correctly without any problems.


    Please click on the gear icon of your text area to open the PROPERTIES menu, from there, click on ADVANCED, and scroll down to find Shrink, and set it as off.


    Thank you
