Hi, The current CSS3 Media Queries working draft only defines dpi (dots per an inch) as a resolution unit. I strongly suggest that you also provide a metric unit for resolution, such as dots per a centimetre (dpcm) or dots per a milimetre (dpmm). 1 inch = 25.4 mm, so 1 dpi = 1/25.4 dpmm, or about .0394 dpmm. So 300 dpi would be 12dpmm or 120dpcm. Metric (or to be more exact SI units) are the internationally preferred system of units, and are also the preferred system in most countries in the world (bar the obvious exceptions like the US). Many people out there (including me) primarily use metric units in their daily lives, and find thinking in inches and other Imperial/customary units uncomfortable. You have already done a very good job in supporting metric units like milimetres in CSS for things like font sizes (most software out there only lets you use points). I hope you'd continue doing this by providing a metric alternative to dpi. Of course, I'm not suggesting dpmm or dpcm as a replacement for dpi. Both should be in CSS3, so that people who want to use dpi can use dpi, but people who want a metric alternative will have one.

If it was, apologies for posting it twice.] __________________________________________________ Do You Yahoo!? Yahoo! Sports - Coverage of the 2002 Olympic Games http://sports.yahoo.com
