How do I get identically written html?

I want to take innerHTML from style and show it in a div demo. But it should be written identically, example
I get:

#one {width: 50px; height: 50px; background-color: red; }

and I need to get;

#one{
  width: 50px;
  height: 50px;
  background-color: blue;
}

So be one below the other, with spaces, as written in notepad ++

function myFunction() {
  var x = document.getElementById("style").innerHTML
  document.getElementById("demo").innerHTML = x;
}

<head>
  <style id="style">
    #one {
      width: 50px;
      height: 50px;
      background-color: blue;
    }
  </style>
</head>

<div id="one"></div>
<div id="demo"></div>
<button onclick="myFunction()">click</button>

Solution

If you style the output element (demo) with the CSS white-space:pre-wrap, its content will wrap the way you need.

From MDN:

pre-wrap

Sequences of white space are preserved. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes.

function myFunction(){
var x = document.getElementById("style").innerHTML;
document.getElementById("demo").innerHTML = x;
}

#demo {white-space:pre-wrap;} /* does the trick */

<head>
<style id="style">
#one{
    width: 50px;
    height: 50px;
    background-color: blue;
}
</style>
</head>
<div id="one"></div>

<div id="demo"></div>

<button onclick="myFunction()" >click</button>
