If you're using a fixed-point width for your font-size settings (e.g.: pixels), then your font size will remain unchanged when the user zooms. If you want the font to enlarge or diminish when the user zooms in/out, then consider using em as your unit (1 em = 100% of the default font size on the user's machine).
