Help with hover on an image on visualforce page

I need help with hovering over an image which shows the list of values from the <apex:repeat> tag: I want the values from the code in the bold below to be shown when i hover over an image something like help bubble(?).

Here is my code

<apex:repeat value="{!dpgEnrollmentGuidelines}" var="dpGuideline" >
                       <td class= "changecolor">
                            <apex:outputText value="{!dpGuideline.Required_for__c}"/>
                        <td onclick="navigateToElement('{!dpGuideline.Id}');">
                        <apex:outputText value="{!dpGuideline.Display_Name__c}"/>
                            <apex:repeat value="{!dpGuideline.Acceptable_Documents__r}" var="accdoc" >
                   <apex:outputText value = "{!accdoc.Acceptable_doc__Name__c}"

You could use the Attribute Title for showing tooltip.

title : The text to display as a tooltip when the user's mouse pointer hovers over this component.

<apex:outputText title="Tool Tip for Control" value = "{!accdoc.Acceptable_doc__Name__c}"
