 Note: the `em` values above could be manually converted to `px` by the author to ensure that the image breakpoints are within a few pixels of the `em`-based layout media queries, resulting in:

 While the `em`-based CSS layout will be reevaulated based on user zoom in all modern browsers (see http://blog.cloudfour.com/the-ems-have-it-proportional-media-queries-ftw/ for a description and functional example) and we can assume the same for the `em`-based image breakpoints, the `px`-based image breakpoints will fall out of sync with the layout when the user zooms in or out.
