@lmccart, sorry to disturb you again and again. I wanted to know that is there any way we can pass objects to the style function.

I wanted to achieve this:

let styles, div;
function setup(){
   background(220);
   div = createDiv('text');
   
   //object which contains styles
   styles = {
      color: 'green',
      background-color: 'blue'
   }; 
   
   div.style(styles);
}

I know that currently multiple styles can be passed as a string separated with ; just like inline CSS.

Also, we can have some functionality for the use of : hover,, : active etc.

@Aloneduckling I don't think that's currently possible
