Is it good practice to place Text Resizing Widgets on your page or should the user change font-size through their browser?
Lately, I've had people tell me that they doubt the utility of the text-resizing widgets; that people who don't know how to resize fonts through their browser would not be able to recognize or use text-resizing widgets. I can't stand this position that people should change font-size only through their browser - and that if users aren't using their browser to change font-size it can only mean that they are ignorant.
I don't see the rational in spending time showing your readers how to change text-size via their browsers after all would they even see or click the link explaining the process if they wouldn't see or use the text-resizing A A A.
It is simpler and easier for most users to adjust text-size on a particular site via an icon than using keyboard commands. Of course CTRL/CMD +/- is simple too but there is more than one way to do things. There is no harm in providing visual clues in interface design - or would you like to get rid of GUIs and go back to UNIX and use Vi or EMACS for your wordprocessing?
Finally a lot of text-resizing problems comes from designers who reduce the size of text, concerned as they are with the visual impact rather than the utility aspect of the site.
