See project:ROUTE#Fractional text display template for usage instruction.

This template displays two lines of text in a text field of route diagram created with {{BS-map}}. It is intended for labeling connecting routes or adding other secondary information, as the second line is smaller and italicized.

• The optional third parameter will provide a wikilink for the text.
• The optional align parameter will left- or right-justify text; if omitted it will default to “inherit”.
• The optional it parameter controls italicization:
  • it=all displays both lines in italics;
  • it=off displays the second line in normal text.
• A separating line can be forced to appear by providing an argument for the parameter "line=anything".
• Background colors can be specified by providing a valid X11 color name (e.g. HotPink) or RGB hex triplet (e.g. #12A3BC) for the parameters "bg1=" (top line) and "bg2=" (bottom line).

Note: This template will disrupt row spacing when used in the first (main) text area.
