Changing the Monospace font

I need to add a custom google font and use it for the Monospace font only. 

I have imported the font from google however I cannot find what class the monospace font is set as? Can anyone assist?

@import url('https://fonts.googleapis.com/css?family=Marck+Script&display=swap');

pre code {
  font-family: 'Marck Script', cursive;
  line-height: 1em;
}

Use this code

@import url('https://fonts.googleapis.com/css?family=Marck+Script&display=swap');
/* cyrillic */
@font-face {
  font-family: 'Marck Script';
  font-style: normal;
