Most of the time when we override Visualforce page, clients/Users many time demand for same Standard page layout inline Help Text bubbles.
apex:inputField and apex:outputField shows their help Text bubble when nested within a pageBlockSection component automatically.
However, there are scenario when helpText Bubble is not displayed at VF page
scenario
----------
1- If we use "Label" attribute of "apex:outputField" , then helpText bubble is not displayed
2- If we set "showHeader=false" of <aapex:Page>, in that case also helpText bubbles is not displayed
We can access the help text within an expression by using the respective $ObjectType global as such:
$ObjectType.Account.Fields.myField__c.inlineHelpText
So I came up with my own idea to display help text at VF page with above two scenarios
<div id="mainContent">
Sample helpText Example
<span class="Custom ToolTip text">
<img src="/s.gif" alt="Help" class="helpIcon" title="$ObjectType.Account.Fields.myField__c.inlineHelpText"/>
</span>
</div>
By Providing "$ObjectType.Account.Fields.myField__c.inlineHelpText" in TITLE attribute of <img> tag..the helpText will be displayed as ToolTip Text
