I have a CSS coding question!

Question

What is the code to make all the images on the page black and white?

Answer 1

Add the css style property

filter : gray;

to all of your image styles

Answer 2

There is no such CSS code, the images are probably converted to greyscale and a different stylesheet or page is used to display the black and white images.  This change REQUIRES additional scripting in JavaScript or server-side implementation

Answer 3

There are none. The images need to be converted to black and white.
