I'm currently busy for a project at theFactor.e which needs the fontsize to be set a couple of point bigger and back again to increase accessibility of the webapplication. This is what I ended up with and this is how it is done:

It all works with 3 stylesheets. In my example default, normal and enlarged. The default works like a normal stylesheet and is added like this to your application:

The other two are compiled to swf when building the application. How do you achieve this you probably wonder. Well you just do a right mouse click on the css file and then select "compile CSS to SWF" like this:

Then you add this peace of code to load the compiled css as a style on runtime:

And that's really it. Look in the source for more details.
