I'm trying to use an FAQ style method for initialing hiding then revealing answers to common questions.

A similar example can be seen on:
Support | Springpad under the section Common Questions.

The problem is that when an item is revealed, by switching the elements style from "display:none" to "display:block", the screen reader will not read it.

Does anyone know if it is possible to use this UI device in an accessible way?

Many thanks!
