Basic Holy Grail Layout The Holy Grail layout renders a sidebar on the left and another on the right. It is a top level page layout.
Important Notes: The sidebars are sticky at and above the medium breakpoint.The primary sidebar transforms into a modal below the medium breakpoint. User can tap a trigger button to activate the modal. trigger_icon and trigger_label props are available for customizing the icon and label text in the trigger button.The secondary sidebar disappears entirely below the medium breakpoint. This sidebar is intended for non-essential information.Holy Grail layout should be used in tandem with Site layout. It would go into the main content area.Tech Doc is a great example of using Holy Grail layout, Site layout, Side Nav, Content Pagination, and Article element together.
