Problem z ikonką ze strony fontello.com

Witam!

Mam problem iż po podpięciu CSS-a z fontello i zaaplikowaniu ikonki do html-a ikonka działa jest tylko problem, że nie mogę zmienić wielkości tego. Używam font-size:72px; w CSS-sie "fontellowym" i nic.

#zegar

	float:right;
	font-family: 'Josefin Sans', sans-serif;
	font-size:70px;
	
	
}

.tile1
{
	background-color:#87CEFA;
	float:left;
	width:240px;
	height:142px;
	margin:5px;
	

	
}

.tile2
{
	background-color:#000000;
	float:left;
	width:240px;
	height:142px;
	margin:5px;

	
}

.tile3
{

{
	background-color:		#48D1CC;
