For loop to generate 10 random colours

Here is my solution with the for loop:

var html = '';
var rgbColor;


function colorGen () { 
  var generateColor = Math.floor(Math.random() * 256 );
  return generateColor;
}

for ( var i = 0; i < 10; i += 1) {
  rgbColor = 'rgb(' + colorGen() + ',' + colorGen() + ',' + colorGen() + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';
}
  document.write(html);

Looks like you're only generating 9 colors. Change it to either i=0 or i <= 10. Looks good otherwise :smile:

Is there some CSS that goes with this? Otherwise the div's don't take up any space and no color is seen.
