Size expressions for bordered boxes

You can define the outer bounds of a box.

The x-Size and y-Size properties specify the inner size of the box; if we specify a box to be 3cm wide and have a 1mm thick border on all sides, for example, the box's outer bounds will appear to be 3.2cm wide. This conforms to the CSS specification.

You can define the outer bounds of a box instead:

Note: Do not use expressions that contain max as only one of its components, such as max/2, to specify the height and width of bordered boxes. Doing so can have unexpected results.
