Here we have filled the entire page.
Creating a Page with SubtractJS
Now, we add a header to the top of the page. The size of the header is subtracted from the available size for this content area automatically.
[Item 1] [Item 2] [Item 3] [Item 4] [Item 5] [Item 6]
Again, we add to the top of the page. The menu bar area is subtracted from the content area that is left after we subtract the header.

This time we add an element to the left side of the page. This is again subtracted from the remaining content area.
