Epub isn’t media – itmdpesnt belong in an MQ.  If you look at the differences between MQ3 and MQ4 you’ll see how they’ve (rightly) simplified it to only includes a core set of thongs

Subject: Is there a CSS media query for EPUB (or, later, PWP)?


the subject line may just show my ignorance. But is there such a beast? Should there be?

I was looking at the proposal for a new style sheet for W3C documents. A sample document is at:


There is  really neat trick, which is based on media queries, on pushing the TOC on the left of the screen (if it is large enough), or to have a small sign on the lower left hand corner of the screen for a narrow screen. It is neat, but if the document is converted into an EPUB, it becomes unnecessary. After all, the EPUB structure requires a TOC; in many respect, that TOC on the left reproduces what Reading Systems do (and they do no matter what). The cleanest would be to control that via a media query…

Just an idea very early in the morning:-)
