Not the Browser Wars Again!
In the last few years, Web browsers have fortunately been approaching a point at which they are all very close to being standards compliant. Unfortunately, however, there are still vast discrepancies in the way they interpret those standards. Furthermore, some things are not yet standard, such as having a text-sizing button. So, although many browsers support the feature, few of them support it in the same way: In Internet Explorer the user can choose from Largest, Large, Medium, Small, and Smallest. Each of these sizes are about two point sizes apart, with the default setting being Medium, or 12 point. Netscape Navigator, on the other hand, supports different percentage sizes: 100% is 12-point text, 200% is about 29-point text, and the user can choose any arbitrary percentage as well.
Getting back to Flash, because there is no way in any browser to get the text size that the user has set the browser to, Flash Web sites potentially offer frustration to users who use that feature. To prevent that frustration, this article walks you through the process of building a "text size getter."
