Reading Code

I am having hard time understanding this code. I understand that red, green, blue store a number after the Math.random () function is executed. I don't understand how the variables rgbColor and html create a circle. Any insight would be appreciated.

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>';
