before and after layout flow

A recurring concept in the i18n community is the layout flow of all visual widgets. For example, a magnitude bar may grow from the left to the right while in the en-us locale, but in the ar-su locale the bar would grow from the right to the left. It becomes convenient to speak in terms of “before” and “after.” The numerical value and the description caption come in an order in layout flow. The numerical value comes before th edescription caption and the description caption comes after the numerical value in layout flow-speak.
