Matching the Salesforce Look and Feel

Apps that resemble the Salesforce user interface look and feel are instantly more familiar to users and easy to use. The easiest way to model the design of your app after the Salesforce user interface look and feel is to use Visualforce. When you use a standard controller with a Visualforce page, your new page takes on the style of the associated object’s standard tab in Salesforce.
