Pomodoro Clock: font awesome not working

I don´t seem to understand why. Any clues?

<!DOCTYPE html>
	<title>Pomodoro Clock</title>
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.3.1/css/all.css" integrity="sha384-mzrmE5qonljUremFsqc01SB46JvROS7bZs3IO2EmfFsd15uHvIt+Y8vEf7N7fWAU" crossorigin="anonymous">
<div id="buttons">
	<h1>Pomodoro Clock</h1>
	<p id="break-label">Break Length</p>
	<p id="session-label">Session Length</p>
<i class="fas fa-arrow-up"></i>

It seems to work for me in that I see the up arrow. Do you see any errors in your browser’s console? What do you see on the page?

Nevermind, missed a comma somewhere. Stupid mistake. Could you delete this thread?
