How to design edit version on a white background?
I'm working on a user profile design for a website. The information (name, email, username, etc) is on a pure white background.
The type of edit feature I want to use involves clicking an edit button and the information is instantly changed to editable fields such as text areas. My problem is that I'm not sure how to style the editable fields. One method I have seen used is a white field on a darker background to give the appearance of the edit field being sunken into the page, but since my background is already white, that doesn't work. Dark styling makes it look like the fields are jumping off the page.
Are there any design styles I can use to make it plainly obvious that these fields are editable now?
