1. Summary

The media types defined by CSS level 2 [CSS21] do not easily fit a device such as a screen reader, which speaks text, but also keeps the audio and the video output synchronized. It seems useful to be able to provide a style sheet for such a device, different from the ‘speech’ media type, which does not have any visual output at all.

However, there has been little interest in defining a high-level ‘reader’ media type.

Current work on Media Queries focuses on defining lower-level media features, which can be combined to let the style sheet author define arbitrary kinds of devices. See Media Queries Level 4 [MEDIAQUERIES-4].
