Template:BS-alt/doc

This is a documentation subpage for Template:BS-alt (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.

This is a subsidiary template to {{BS-overlap}}. This template takes a single argument, which is the name of a route-map component, and produces alt text for that component.

To describe the icon "File:BSicon ID.svg", add a line:

|ID=Description of the icon

to the template. The ID is a pictogram ID. An example pictogram ID is utSTRlg, which identifies the image File:BSicon utSTRlg.svg ; this ID has the prefix "ut", the root "STR", and the suffix "lg". The corresponding entry in this template's source code is:

|utSTRlg=Urban tunnel from right

Directions in alt text are written from the driver's viewpoint. The driver faces down the page; in this example the tunnel comes from the driver's right and then goes straight ahead.

Entries in this template should be sorted first by core (using a standard en_GB locale), then by prefix, then by suffix.
