Question

<!DOCTYPE html>
<html>
<head>
</head>
<body>
  <p id="timer"></p>
  <script>
  var a = 30;
  var b = 1;

  var c = document.getElementById('timer').innerHTML = a - b;
 </script>
</body>
</html>

Thanks for taking your time to look at this! 感谢您抽出宝贵时间来看看这个！

How would I show VARIABLE C inside the HTML TITLE tag?? 如何在HTML TITLE标签内显示VARIABLE C ？

so: 所以：

<title>SHOW WHAT VARIABLE c IS EQUAL TO</title>

The point for this is to make a countdown timer that will show your time in your tab so you don't have to keep checking. 这样做的目的是制作倒数计时器，在计时器中显示您的时间，这样您就不必继续检查。 Also, right now it just subtracts 1, how would I make it KEEP subtracting?? 另外，现在它只减去1，我如何使其保持减法？

THANK YOU!! 谢谢！！

I appreciate it 我很感激
