Line-based placement
Using the Grid I defined in example 1, I am positioning the elements in my markup (six divs with a class of box and classes from a to f) using line-based placement properties. This example is more verbose than it needs to be as a demonstration of the properties. In reality, if an item will only span one grid track you may omit the -end
value.
