    How to change radio button and checkbox size?

    I tried changing the radio button style yesterday and it solved the issue.  I still need to try out with bigger radio buttons and checkboxes.

    To change the size of both radio buttons and checkboxes, you need to inject the custom CSS codes below.

    .form-radio, .form-checkbox{

       transform : scale(2);

       height : 40px;



    You can change the height according to your request. 

    Here is the user guide on how to inject custom CSS codes.


    I hope this helps. If you have further questions, please let us know.
