Switch CSS of a rich:datascroller

Question

I wanna switch the styles the datascroller uses to shows the selected page. Is it possible?

<f:facet name="footer">
    <a4j:form>        
        <rich:datascroller styleClass="wrap-paginacao" for="estabelecimentoGrid" boundaryControls="hide" stepControls="show"  fastControls="hide"  >
            <f:facet name="previous">
                <h:graphicImage value="/home/img/previous.png"/>
            </f:facet>

            <f:facet name="next">
                <h:graphicImage value="/home/img/next.png"/>
            </f:facet>
        </rich:datascroller>
    </a4j:form>  
</f:facet>

override .rf-ds-act class of richfaces to whatever you want..

if this does not suffice you right click scroller component and click on inspect element using firebug you will get which css to override.
