How can I toggle visibility of an element on a Visualforce page using a button?

I know there must be 10 different ways to do this but I am reaching my knowledge limit here and need some help.

I have a table on my visualforce page which is pulling a list of all Workstep__c records that are related to a defined Sub_Order__c object.
Here's a much simplified version of my list:
<apex:pageBlock >
        <apex:pageBlockSection columns="1">            
            <apex:pageBlockTable value="{!wsList}" var="ws">   
                                             
                <apex:column headerValue="Name" value="{!ws.Name}" />                   
                <apex:column headerValue="Duration" value="{!ws.Duration__c}" />
                 
            </apex:pageBlockTable>
        </apex:pageBlockSection>
    </apex:pageBlock>
I need to have a button or a link at the top of the page that, when pressed, toggles visibility for any Workstep__c records on the list that have a Duration__c value of 0.

Right now I have a bunch of style classes defined in CSS and I've applied conditional styling to each column in order to hide the rows with a duration of 0, and it works just fine (though it's messy.. still trying to figure out how to clean it up a bit), however I want to be able to toggle the visibility of those rows on or off with a button. Suggestions for what direction to look?

Hi Justin, using pure Javascript you can do this:
 
document.getElementsByClassName('appBanner')[0].style.visibility='hidden';

There are other ways to get this done using jQuery, but I assume you don't know jQuery .... yet.
