Tryit Editor v2.9

Edit This Code:
<!DOCTYPE html>
<html>
<body>

<p>The code element does not preserve whitespace and line-breaks.</p>
<p>To fix this, you can put the code element inside a pre element:</p>

<pre>
<code>
var x = 5;
var y = 6;
document.getElementById("demo").innerHTML = x + y;
</code>
</pre>

</body>
</html>
