preview just shows a blank page??? Help?

When I preview the code that I did in workspaces as I followed along all that it shows is a blank page... I think my code is the same as the video, am I missing something? uncaught syntax error?

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Circles</title> <link rel="stylesheet" href="css/styles.css"> </head> <body id="color"> <script src="js/script.js"></script> </body> </html>

var html = '';

for ( var i = 1; i <= 10; i +=1 ) { html += '<div>' + i '</div>; } document.write(html);

You forgot a plus sign after the i. Also you forgot another ' after the closing div tag. This should fix it:

var html = '';

for ( var i = 1; i <= 10; i +=1 ) {
  html += '<div>' + i + '</div>';
}
document.write(html);

Hope this helps and happy coding! ~Alex
