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