Change border color on check box upon selection?

[FlexPackPRO]

Is there a way to make these three options checkboxes, and have the one selected change to a thicker, red border only when selected?

You can add check-boxes next to them, but if you want the actual boxes to act this one you would need to use buttons and a custom-made script to "select" and "unselect" them when the user clicks them.

How about make them buttons. Then add a hidden text field to save/control the state.
