Website in Mourning – how to make entire website Black and white / greyscale quickly

so i was just asked to make a school web site black and white  – in mourning  for the death of the Queen. I know Divi has a Greyscale option for its modules so i tried this on the body in my child theme style sheet: body { -webkit-filter: grayscale(100%); -moz-filter: grayscale(100%); -ms-filter: grayscale(100%); filter: grayscale(100%); } and it worked! entire website is now tastefully grey! UPDATE: you may have to do some hefty site cache clearing though so bewarned, and maybe add !important too

so i was just asked to make a school web site black and white  – in mourning  for the death of the Queen.

I know Divi has a Greyscale option for its modules so i tried this on the body in my child theme style sheet:
body {
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
filter: grayscale(100%);
}
and it worked!

entire website is now tastefully grey!
