I didn’t see any option to change its background color in the customization to resolve this. Changing body affects the font color, but also the font color across all screens.
Is there a way to change the background color? Maybe via custom CSS or something?
If so how?
Thank you for posting your question. Unfortunately, without custom pages, it’s not possible to edit the background or font color of these fields. We already have a feedback page about this issue here: Make it possible to change background color of disabled field on Customization Options for New Universal Login. I encourage you to share your feedback under mentioned post. I will try to bring the team’s attention to this problem, as there are already several user experience problems with these settings.
