You can customize the page layouts for record detail and edit pages, Self-Service portal pages, Salesforce Customer Portal pages, and the case close page. Page layouts control the layout and organization of buttons, fields, s-controls, Visualforce, custom links, and related lists. They also help determine which fields are visible, read only, and required. Page layouts can include s-controls and Visualforce pages that are rendered within a field section when the page displays. You can control the size of the s-controls and Visualforce pages, and determine whether or not a label and scroll bars display.
