I am using <p:growl> component of PrimeFaces 3.2 to show faces messages. I would like to customize its position so that it appears on the left side instead of the right side. 
I tried the following:
<h:head>
    <title>Facelet Title</title>
    <style type="text/css">
        .ui-growl {
            position:absolute;
            top:20px;
            left:20px;
            width:301px;
            z-index:9999;
        }
    </style>
</h:head>
<h:body>
    <h:form id="frm">
        <div id="add">
            <p:growl id="growl" showDetail="true" sticky="true" autoUpdate="true"/>
            <h:panelGrid columns="2" >
            ...
But it did not work. Where was I wrong?
