Alternatywy CSS do style = „display: none”

Implementuję bazę komponentu JSF, w której musisz zastąpić używane css lub użyje domyślnego css. Próbuję ukryćdiv i próbowałem ustawićrich-panelbar-header-act class style="display:none", ale potem pobiera domyślne css. Czy istnieje sposób na dodanie atrybutu stylu dorich-panelbar-header-act (odkąd muszę zaimplementować klasę), która ukrywadiv? Poniżej umieściłem mój css i html

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;
}

HTML:

<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>
