Tip: Resizing text on Windows with Internet Explorer
In the ongoing debate about whether to use pixels or ems to size text with CSS, there has been the problem that pages with fonts set in pixels cannot be resized in Internet Explorer 5 on a Windows platform. However, there is a way to override this. Select Tools->Internet Options->Accessibility->Ignore font sizes specified on web pages. Then text can be resized as wanted just like on most other browsers. Keep in mind that most users are not likely to know about this. Hopefully people with accessibility problems know it.
