Yet we have all of these other measurements such as points, ems and >percentages that screw things up. <snip/> We set screen resolution in pixels. because pixels relate to the physical properties of our hardware. We also need to specify the number of pixels per inch. That way we can set the physical resolution to work well with the hardware, but set the logical resolution to something that works well with our eyes. Setting measurements in pixels ignores the second step. Sometimes you can olny specify in pixels though (when dealing with rasterized graphics, for example). The question "How does this site look at 800 by 600" is actually meaningless. You need to specify the pixels per inch as well. Andrew -- Andrew McFarland UNITE Solutions http://www.unite.net/
