How do I change the color and style of the Shopper and Stock Remaining Counter widget?

Shopper and Stock Remaining Counter comes with several preset styles you can choose from. Simply open the app and scroll down to the  Styles section to choose a preset.

Alternatively, if you'd like to do something different, select the  Custom preset then tweak the style fields to your heart's content. 

Finally, if you have HTML / CSS experience, you can also add in your own custom CSS via the  Custom CSS field in the Advanced Settings section.
