Endless Prompt doesn't let page-HTML refresh!

I was doing one challenge of the JS course. Quick review: there is an infinite prompt, which might put some info on the page. Only when I break the infinite loop, the whole info, that was supposed to be gradually adding to the page, instantly appears.

the code:

var message = '';
var student;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML += message;
}

function getRand256(){
    return Math.floor(Math.random() * (256));

}

function getRandColor(){
return 'rgb(' +getRand256()+','+getRand256()+','+getRand256()+')';
}

function getStudent(sName){

  for (var i = 0; i < students.length; i += 1) {

    if(sName === students[i].name){
  var lameP = '';
 for(var N in students[i]){
   lameP+="<p>"+ N +": "+ students[i][N] +"</p>";
 //print("<p>"+ N +": "+ students[i][N] +"</p>");
 }

  print("<div style = 'border-bottom: 2px solid red; border-left:"+getRandColor()+" solid 2px; padding-left:60px'>"+lameP +"</div>")
    }

    }

}

while(true){
var name=prompt("Insert Stud name!");
  if(name ==='quit' || name===null) break;
 getStudent(name);

}

return Math.floor((Math.random() * 256) + 1 );

If you fix this, what happened?

Nothing of interest, really, because it will only affect color representation (as rgb(x,y,z) accepts (as x, y and z) numbers 0-255, which would ruin the code, as now we can get numbers 1-256, if we get a 256 even once, the program breaks (as we have Math. floor, and Math random returns [0;1) , we would never get 256 in my example)). So, this doesn't really help the topic.
