Boldface numbers

You can use bold to highlight user interface elements such as numbers in instructional text. Don’t use it just for emphasis. Only use one treatment at a time (color, bold, italics, indentation). If the ghost text in a form field is already italicized or a distinct color, don’t make it bold too.
