CSS not changing font size!

HTML & CSS
1

I just a beginner here and trying to practice html and css; however, im
having difficulty understanding why the class 209CrystalCt is not
working. I’m just getting a regular html output on the screen. Here is
the html file I have.

HTML Code:

	<!DOCTYPE html>
<html>
	<head>
		<link type="text/css" rel="stylesheet" href="stylesheet.css"/>
		<title> Fahman Resume </title>
	</head>
	<body>
		<div id="header">
			 <p class="209CrystalCt"> 
				Fahman Khan 
			</p>
			<p class="209CrystalCt">
				209 Crystal Ct
			</p>

		 </div>
		<div class="left"> </div>
		<div class="right"> </div>
		<div id="footer"> </div>
	</body>

</html>

Here is the css file

	p.209CrystalCt
{
	font-size:32px;
	color:white;
}

#header
{
	height:100px;
	width:1300px;
	background-color:#151515;
	border-radius:10px;
	
	
}
.left
{
	width:200px;
	height:600px;
	background-color:#424242;
	float:left;
}

If the solution is found, may I know why this code did not work. Thank you in advance!

Well you need to format your code (edit your post and hit the </> button to make it code formatted.

Classes can’t begin with a number though. So 209CrystalCt is invalid since it begins with a 2. Change your class/HTML.
