Could someone explain why this code doesn't work?

var html = '';

var red = Math.floor(Math.random() * 256 );

var green = Math.floor(Math.random() * 256 );

var blue = Math.floor(Math.random() * 256 );

var rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';

for (var i = 0; i < 10; i++) { html += '<div style="background-color:' + rgbColor + '"></div>'; }

document.write(html);

This code produces 10 dots of the same colour, I'm struggling to understand why this is not a valid solution : ( Could someone break it down for me Also i'm sorry i don't know how to include a snapshot of the code instead of writing it in :(((

To take a snapshot click the camera icon in the upper right corner of the workspace. This will create a link that you can then copy/paste.

What are you trying to do with the dots? You want them to be different random colors?

The colors are the same because the red, green and blue variables produce only one value when the script runs.

This code creates a random color, but only once. Then the loop creates 10 elements of that same color.

If you want each element to have a different color, you'd need to put put the part of the code that picks the color inside the loop (where "red", "blue", "green", and "rgbColor" get assigned).
