*SOLVED* Custom CSS to rid whitespace on ebooks

[Hermes]

Using the cbz files to read ebooks. Had to fix a problem with the images not centering on mobile (fixed with css). The problem now is that I have whitespace above and below the centered image. See the attached screenshot.      

Does anyone know of any custom css to turn this whitespace to black for nighttime reading?

i use their extensions for chrome and firefox, now all my sites are in 'dark mode' no matter how Apple the developer wanted to be (i mean white webpages)

I am using the mobile app and have a user base that is cross platform. That's why I am looking for a CSS solution, rather then asking my multiple users to each download browser extentions.

since the extension injects css to achieve what it does i suggest investigating the only suggestion you've received thus far instead of dismissing it immediately
