Change style of div

Question

Is there any way to make the last line of the code below to random a background color for all the div created from the "for loop"?
var x=Math.random()*3;
var random=Math.floor(x);
var list=new Array["red","blue","green"];
var bgcolor=list[random];
for(i=0;i<10;i++){
var ele=document.createElement("div")}
ele.style.width="50px";
ele.style.height="50px"
ele.style.background=bgcolor;
