This is a loop from a challenge. It's not running; why?
var html = '';
var red;
var green;
var blue;
var rgbColor;
for(var i = 1; i <= 100; i += 1){
red = Math.floor(Math.random() * 256 );
green = Math.floor(Math.random() * 256 );
blue = Math.floor(Math.random() * 256 );
rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
html += '<div style="background-color:' + rgbColor + '"></div>';
}
document.write(html);

Your JavaScript code looks fine to me.
Have you added the script to an external file? Without a reference to the file it won't display anything to the browser :-)

Fixed markdown for the posted code. If you're curious about how to add markdown like this on your own, checkout this thread on posting code to the forum . Also, there is a link at the bottom called Markdown Cheatsheet that gives a brief overview of how to add markdown to your posts.
