I'm using O365 classic forms. I have five Yes/No controls in the form. I want to change background color of the check boxes to orange when they are clicked. At the moment the background color changes to blue(default color) as below when it is clicked.
Can this be done using CSS, if so could someone guide me on how to do this as I'm not much familiar with CSS.
you can do something very easy with "formating rule" to change the background of your control, but this will change the background of all you control, not just the CheckBox.
For exemple :
Else you can use pure CSS, but you will need to build your css....
Here some link that can help you :
