Styling Visualforce Pages

It’s easy to style a Visualforce page, either by mimicking the look and feel of a standard Salesforce page, or by using your own stylesheets or content types.

Many Visualforce components have a style or styleClass attribute. Defining either of these attributes allows you to associate CSS code with the component. Custom CSS code enables you to change the default visual style of a component, including its width, height, color, and font.
