Alternativas CSS para style = “display: none”

Estou implementando uma base de componentes JSF onde você deve substituir o css sendo usado ou ele usará seu css padrão. Estou tentando esconderdiv e eu tentei definir orich-panelbar-header-act class style="display:none", mas então ele puxa seu css padrão. Existe alguma maneira de adicionar um atributo de estilo pararich-panelbar-header-act (desde que eu tenho que implementar a classe) que esconde odiv? Eu incluí meu css e html abaixo

CSS:

element.style {
}

.rich-panelbar-header-act {
background-image: url(/spot-main-web/a4j/g/3_3_3.Finalorg.richfaces.renderkit.html.GradientA/DATB/eAGLj48PDQ1lBAAJswIe.html);
background-position: top left;
background-repeat: repeat-x;
vertical-align: middle;
color: #FFF;
background-color: #555;
font-size: 11px;
font-weight: bold;
font-family: Arial,Verdana,sans-serif;
}
.rich-panelbar-header-act {
border: 0 solid red;
padding: 0 1px 1px 5px;
cursor: pointer;
}
user agent stylesheetdiv {
display: block;
}

body {
font: 12px/17px Helvetica, Arial, Verdana;
}

HTML:

<html version="XHTML 2.0" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
<div class="rich-panelbar rich-panelbar-b " id="j_id95" style="padding: 0px; height: 400px; width: 500px; none">
<div class="rich-panelbar rich-panelbar-interior " id="j_id96" style="none"><div class="rich-panelbar-header " style=";">Leverage the whole set of JSF benefits while working with AJAX</div><div class="rich-panelbar-header-act " style=";;;;display: none;">Leverage the whole set of JSF benefits while working with AJAX</div><div class="rich-panelbar-content-exterior" style="display: none; width: 100%;"><table cellpadding="0" cellspacing="0" style="height: 100%;" width="100%"><tbody><tr><td class="rich-panelbar-content " style=";">

Ajax4jsf is fully integrated into the JSF lifecycle. While other frameworks only

give you access to the managed bean facility, Ajax4jsf advantages the action and value

change listeners as well as invokes server-side validators and converters during the

AJAX request-response cycle.</td></tr></tbody></table></div></div>
