Email preheaders, Showing text in the body

When I put my preheader in my email, it is also showing the first line of my email text. I do not want that. How can I make it to where it only shows what is in my preheader and not the rest?

Heres what I am using for my preheader


<style type="text/css">
	.ReadMsgBody {width: 100%; background-color: #ffffff;}
	.ExternalClass {width: 100%; background-color: #ffffff;}
	body	 {width: 100%; background-color: #ffffff; margin:0; padding:0; -webkit-font-smoothing: antialiased;font-family: Georgia, Times, serif}
	table {border-collapse: collapse;}
    .preheader { display:none !important; visibility:hidden; opacity:0; color:transparent; height:0; width:0; }	

</style>


</head>

<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" yahoo="fix" style="font-family: Georgia, Times, serif">

 <span class="preheader" style="display: none !important; visibility: hidden; opacity: 0; color: transparent; height: 0; width: 0;">Quickly target high-value physicians and facilities to grow your home care referrals! </span>
