I'm trying to write css media queries for landscape and portrait orientations.
With widths of 1024 pix and wider, you think that 1024 pixels is enough to have 2 columns instead of 1.
But does any ebook software allow the user to specify single page layout or double page layout for landscape orientation? If yes, how do you use conditional CSS media queries to specify when there is only 1 column as opposed to 2? For example, do later versions of ibooks with the retina display let you set one column and two column mode for landscape orientation?
Update: I see the Kindle app for Android lets you specify 1 or 2 columns for landscape orientation. Gitden on Android does the same. ibooks 3.13 (for ipad 1) has no option; it just shows 2 columns by default for landscape.
When processing the media query for a 1024 px image, does it consider the pixel width for each page to be 512? Or does it consider the width of a 2 column page to be the combined total (512+512)?
