A friendly suggestion -- using dashes is somewhat iffy when browsers with various font definitions come into play.  I've had better success simply writing a text entry containing the maximum number of M/W characters possible into the element, and then
changing the font-color to be the same as the background (normally white). Also, I use the "style" definition to force the width to be a fixed number of pixels (way larger than essential), so that the thing won't change shape on the screen when the
contents get tweaked.
