This example just takes all the elements of #content and puts it into a named flow, which is then flowed into an explicit slot. It's an entirely-too-verbose way of expressing the same thing as examples 1-3, but I wanted to introduce the idea of moving content to a named flow and getting it into a template. >> A simple header for each page: >> >> #content { overflow-style:paged-x; } >> @master-template { >> template-slots: header, content; >> <slot-syntax>(header) { >> content: "title string"; >> } >> <slot-syntax>(content) { } >> } > > What's the purpose of 'template-slots' -- to define an order for the slots? It's both to create the slots and define an order. >> A simple footer for each page: >> >> #content { overflow-style:paged-x; } >> @master-template { >> template-slots: content, footer; >> <slot-syntax>(content) { } >> <slot-syntax>(footer) { >> content: "author string"; >> } >> } > > If 'template-slots' define an order, chances are that the 'footer' > slot will get some content flowed into it.

In this example the footer slot only gets the generated content from its content property. >> Displaying two articles side-by-side: >> >> .article1 { overflow-style:paged-x; } >> .article2 { flow-into:second-article; } >> @master-template { >> template-slots: content, right; >> <slot-syntax>(content) { >> width: 40%; >> padding: 5% >> float:left; >> } >> <slot-syntax>(right) { >> flow-from: second-article; >> width: 40%; >> padding: 5% >> float:right; >> } >> } > > Hmm.

I guess I don't understand what it > does. The content slot gets all of the content from .article1 Perhaps I wasn't clear enough in the first series of examples, but 'content' is a special term in a master template that is the explicit expression of the implicit slot that takes all of the paginated element's content.
