    To adjust the text box in the matrix, you may inject the following CSS code:


    .form-matrix-values .form-textbox {

      width: 200px;



    Please let us know if this helps.

    That did the trick.

    BTW: Where can I find the list CSS class identifiers used in JotForm?

    I tried going to the FireBug site and getting the list, but couldn't locate

    On behalf of my colleague, you are kindly welcome. :)

    I'm afraid that we do not have any comprehensive list of classes used in JotForm forms.

    In most modern browsers, you can generally see the class of any element by right-clicking on it, and selecting Inspect Element from the menu that opens.

    I hope this helps, John. Please don't hesitate to open a new thread for any other issues or assistance you may need with your forms, we will be happy to help.
