Custom label in visualforce page and apex Class

Custom labels are custom text values that can be accessed from Apex classes or Visualforce pages. The value of Custom label can be static or dynamic from visulaforce page and apex class. The values can be translated into any language Salesforce supports. Custom labels enable developers to create multilingual applications by automatically presenting information (for example, help text or error messages) in a user’s native language.
In this article I’ll demonstrate how to use custom labels in visualforce page and apex classes.

<apex:page tabstyle="Account">
       <apex:outputtext value="Custom lable value is : ">
       <apex:outputtext style="font-weight: bold;" value="{!$Label.DemoCustomLabel}">
