How can I make the quantity amount font the same in both the payment and widget

I successfully adjusted the registry widget font to be the same size as other form content. However, the quantity font did not change.  I would like to adjust the quantity font to be the same as the shown in the payment tool.

Thanks,

Hi,

You can add this custom css code to make the fonts similar:

.checklist input[type=number]{font: 0.75em Arial;}
