Solution to Challenge

So uhm...I thought the challenge was abit easy so I tried to play around and nested another for loop inside and used an array for the colors...

after a good 20 - 25 minutes... here is what i got...it was a good exercise..

<script>

var html = '';
var color = ['red', 'green', 'blue'];
var rgbColor;

function getColor() {
  var num = Math.floor(Math.random() * 256 );
  return num;
}

 for ( var i = 1; i <= 10; i++ ) { 

   for ( var j=0; j<3; j++) {

    color[j] = getColor();  
    rgbColor = 'rgb(' + color[0] + ',' + color[1] + ',' + color[2] + ')';  

   }

   html += '<div style="background-color:' + rgbColor + '"></div>';

}

document.write(html);

</script>

Just sharin'!

Peace v ^_^ v
