/* 0.4em is exactly equal to 0.5ex which is exactly equal to the distance that 'middle'
causes the centerpoint of the image to be from the baseline. Since the centerpoint
is 1em above the bottom of the image, that means the bottom of the image has to be
moved -0.6em so that it is at the same position as it would be with 'vertical-align'
set to 'middle'. The bottom of the image is a further 0.6em+1em-1.5em from the bottom
margin edge of the whole replaced element, which is what needs to be moved away from
the baseline. So -(0.6em+(0.6em+1em-1.5em)) = -0.7em is the distance to move. */;
