The Home Straight

Back to your index.html file as it was after Page 25.

You will need to add this code before the <script> tag:

<style>
  body {
    background-color:green;
  }
  div {
    text-align:center;
  }
  img {
    height:23vmin;
  }
</style>
<body>

Then replace the first for loop with this code:

  var n=0;
  for (var r=0; r<4; r++) {
    document.write('<div>');
    for (var c=0; c<4; c++) {
      document.write(s1 + arr[n] + s2);
      n++;
    }
    document.write('</div>');
  }
And add this line to the very end of your file:

</body>
