Every header topic shows a table at the start of the topic. This table reflects the page setup. PDF ProCSS publishing allows for 5 different header element places in one header. The rest of the table has a grey background. You can add contextual information here but remember, this won't publish. A header definition is only possible for the top part of the page.
Every header topic has an image embedded. This image explains the location of the header areas. The exact position of the cells on the page depend on the definition of the margins in the media object. The position of the top-center area can be modified in the CSS.
You can add header information in different ways:
- Insert a file object like a logo in one of the cells.
- Type text.
- Embed a topic.
- Use one of the building blocks listed in the header topic. These building blocks can contain references to the book Print properties, styles, etc.
