For all question types containing radio buttons or checkboxes ('Categories - Single answer', 'Categories - Multiple answers', 'Tables - Single answer' and 'Table - Multiple answers'), there is an additional option to change the size of the radio buttons and checkboxes. The option is available in the ‘EDIT' - 'Design' tab when editing a theme (Theme customisation). In the 'Radio buttons and checkbox' segment (PC theme customisation) or 'Mobile phone custom icons' segment (Mobile theme customisation), you can choose any size of radio buttons or checkboxes (from 18 to 55 px for PC and from 20 to 55 px for mobile).
The selected setting is applicable for the whole survey (all questions with radio and checkbox buttons), but not to a device used for accessing the survey. Different icon sizes can be chosen for surveys shown on personal computers (and tablets) and surveys shown on mobile phones. This functionality enables us to, for example, only enlarge icons on mobile phones, where this is recommended because of smaller screen sizes, and not on personal computers and tablets, where icon size remains the same.
