how to add a new class to the editor's iframe body?

@ryzraz what do you mean an existing class ? Even thought, setStyle can replace properties of existing classes by overwrite each classes as you like..

example:::

editor.setStyle(` 
     .gjs-toolbar { 
          background-color: #595e61;  /* replace the background color of toolbar */
     }   
`);

Hi @ryzraz you can use setStyle as below

editor.setStyle(` 
   .your-selector {
       color: white;
       background: red;
   }
`);

hi @ploutos27, its an existing class .. i wanted here to add that class to the body of iframe..!
