    How to make headers of matrix to bold and fixed width?

    Asked by zubeida on August 05, 2015 at 09:08 AM


    Would like to know what should I do to bold the first row in all my matrix tables (the part highlighted in yellow)? 

    Also, would like to ask if it is possible to increase the font for the same row (highlighted parts) while still maintaining equal gaps/distance between all choices (from strongly disagree to strongly agree).

    Thank you.

    It seems that you have already provided the font size for the column headers of matrix.

    If you want to increase the font-size, you may try increasing the number and see the change on your JotForm. 

    Please inject the following CSS code to your JotForm to change the width of all the column headers of matrix and to bold:

    .form-matrix-column-headers {

    font-weight: bold;

            width : 50px;


    Please refer to the guide below that can help you in injecting custom CSS code.


    Hope this information helps. Let us know if you need any further assistance. We will be happy to help.
