I know so far that I can add a page background, however it's not yet what I wanted.

Is it possible to [1] make a picture (the background) black and white and [2] change the contrast so the picture will be very dark or very bright, using codes in CSS?

Code I'm using now in CSS .WikiaPage .WikiaPageBackground { background-image: url(https://vignette4.wikia.nocookie.net/blitzbrigade/images/4/41/Microsoft_Store_Reception_1.1.jpg/revision/latest?cb=20170104173831); background-repeat: repeat-y; background-attachment: fixed !important; background-size: 100% !important; border-top: 8px solid goldenrod !important; }
