When we read a page, some of what we see is content, and some is the infrastructure layer.

In a fixed format document the infrastructure layer is often known as ‘page furniture’. This includes page numbers, headers and footers, and at the document level it might include standard messages about sustainability, publication dates, copyright and the like. It is often prepopulated in page templates before content is added.

In online documents, the infrastructure layer will include breadcrumb trails, menus and links to other pages, and all the icons and tabs you can see in your browser and desktop.

How do we know what’s content and what’s infrastructure? When we read the content aloud, infrastructure is everything we ignore.

Why does it matter? Page furniture includes important aids to navigation, but done poorly it can confuse.

How this helps
When designing a series of pages or documents, the infrastructure is there to link them as a system, and help readers navigate.
