Displays any arrangement of layouts and components beneath a billboard or card header that is flush with the edge of the page. Similar to a form layout, this is a top-level layout and cannot be nested within other layouts. The header content layout is ideal for landing pages, dashboards, and record views.
To add a header content layout to your interface from design mode, drag out either a CARD HEADER or BILLBOARD HEADER from the interface palette.
See also: Header Content Layout style guidance
The contentsWidth parameter sets the maximum width of the contents area. When set to any value other than "FULL", the contents are horizontally centered with equal margins on each side.
Keep the following in mind when using this parameter:
"EXTRA_WIDE" on a Narrow site), the contents fill the available space and no horizontal scrollbar is introduced."FULL" regardless of the configured value. This matches the behavior of a!formLayout()."EXTRA_WIDE" is 1440px. The "EXTRA_WIDE" value corresponds to 1440px, matching the "EXTRA_WIDE" column width available in a!columnLayout().Related style guidelines:
The footer parameter accepts a card, billboard, or list of cards and billboards (using a!cardLayout() or a!billboardLayout()). The footer renders edge-to-edge at the bottom of the page.
Keep the following in mind when using this parameter:
true, the footer is not pinned to the bottom of the page during scrolling. The footer remains below contents and scrolls with the page.Related style guidelines:
The backgroundMedia parameter accepts both images and videos. If you want to use a video for your billboard media, there are a few constraints to consider:
For more information, see the Web Video Component page.
You can place a single pane layout inside the contents parameter of a header content layout.This is useful when you need a consistent header that spans across multiple, independently scrollable content sections.
When a pane layout is used in a header content layout:
The following examples demonstrate the header content layout.
To experiment with examples, copy and paste the expression into an interface object.
This example uses a billboard layout within the header content layout. It displays the following interface.
See the page on Billboard Layouts for more information on billboards and the SAIL Design System: Billboard Layout for guidance on when to use each overlay style.

This example uses a fixed header within the header content layout. It displays the following interface.
Note that this pattern contains two empty a!cardLayout() components to help you see the scrolling behavior with a fixed header. These components have no other purpose.
See the SAIL Design System: Header Content Layout for more information on fixed headers.
Copy and paste this example into an interface object to experiment with it.
