    How to change font size and column width in the matrix (survey tools)

    Asked by WCSPC on September 02, 2013 at 03:07 AM

    Hi we are designing a survey and love th tools. The only problem that we have is that the matrix auto adjusts font size & column width and we are worried that the font size is too small for some of our users.

    Can we change this easily?

    Thank you

    If you want all textbox of your matrix field increase the height and width. Also, for the header font size to adopt to the size of the matrix. Kindly inject this code on your form. (Change the value of the width and height according to your preference)

    .form-matrix-values .form-textbox {

    font-size: 100%;

    width: 100px;

    height: 50px; 


    .form-matrix-column-headers, .form-matrix-row-headers {

    font-size: 100%; }


    Follow this guide on how to inject this codes

    1. Click Setup & Embed
