Thanks for your answer. I had not considered that users might not have control over the browsers option settings on their desktop.

I understand your reference to “educating the user” as providing instructions on how to use their browsers or assistive technology to change text size, for example.

One problem with this approach is that users may not have ownership of their desktops, which may prevent or limit the setting of different text sizes, background colors, etc.

Another is that people may not be able to follow or to remember instructions on how to use browser-based, text-size switching; using a widget would be easier.

I have posted several articles about ideas for adding features such as text-size enlargers. One, which contains links to some of them, describes my effort to educate users. See “Browser-Based Text/Font Size Switching: Dissatisfaction & Solutions” at http://bit.ly/6NBTDa

Given browsers offer the ability to change text size, I’ve been advocating educating the user rather than adding a text-size widget.
