How to Change Background Color of Random Value Generator?

I've tried making the very last field bg be a light yellow. I've tried injecting CSS in the widget and also in the form design. Please help! This is the color I would like it to be: #FFFFCC

The field is Reference#

My understanding is that you want to change the background color of the text box of the Random Value Generator widget. If yes, then please insert this CSS code inside the widget:

#valueContainer {
background-color: #FFFFCC;
}

Select the widget and the click the "Widget Settings" button. After that, go to the "Custom CSS" tab. Paste the code and then click the "Update Widget" button.

Hope that helps. Thank you.
