I should add that it's more beneficial to teach the user to use the tools that come with their web browser to set their preferred font size, where they hold down the Ctrl key and use + or - to make things bigger or smaller, and Ctrl-0 to reset back to the default.
If only there was a JS API that could hook in to the browsers' native functionality.
