What about my version?

var html = ''; var red; var green; var blue; var rgbColor;

function randomColors() { red = Math.floor(Math.random() * 256 ); green = Math.floor(Math.random() * 256 ); blue = Math.floor(Math.random() * 256 ); rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')'; return html += '<div style="background-color:' + rgbColor + '"></div>'; } var counter = 0; do { var colorRandom = randomColors(); counter++; } while (counter < 10); document.write(html);

How so you see the div's with no dimensions? Or do you have some CSS to go with this?

If not, you could give the div's some height using inline styles:

  return (html += '<div style="background-color:' + rgbColor + ';height:2em"></div>');
