Can i use CMYK in css?

Answer 1

Unfortunately the answer is no.

CMYK is primarily used in printing and we use CSS to apply styling to the HTML page, which display on digital screens.

You may consider to use additional plugins via Sass or SCSS but I'm not sure if the conversion works 100% correctly.
