Change the background color of "Erscheinungen" checkboxes so every second is the same

- Optional: there can be many items here (up to 52 per year). It would be more convenient for the customer if we could work here with a table where the rows are color-separated. For an example see screenshot.

You can accomplish that with the Form Designer tool:

1) Click on CSS tab.

2) Click on the check box you want to apply the background color change.

3) Click background-color property and apply any color you want.
