[css3-mediaqueries] Handling non-square pixels from fantasai on 2007-08-21 (www-style@w3.org from August 2007) (original) (raw)

Proposed changes:

http://www.w3.org/TR/css3-mediaqueries/#device-aspect-ratio

In this specification, aspect ratio is defined as the number of

horizontal pixels over the number of vertical pixels.

change to

| In this specification, aspect ratio is defined as the horizontal | length of the device's display divided by its vertical length.

http://www.w3.org/TR/css3-mediaqueries/#resolution

The �resolution� media feature describes the resolution of the

output device, i.e. the density of the pixels.

Add

| When querying devices with non-square pixels, in 'min-resolution' | queries the least-dense dimension must be compared to the specified | value and in 'max-resolution' queries the most-dense dimensions must | be compared instead. A fixed 'resolution' query never matches a device | with non-square pixels.

(Alternatively we could allow two values to query each dimension independently, but I don't think this is useful.)
