! The 0.3em comes from the following:
|
|
!
|
|
! * The font is 1em high
|
|
! * The line height is 0
|
|
! * The half leading is therefore -0.5em centered around the middle of the font
|
|
! * The baseline is 0.2em from the bottom of the font
|
|
! * Thus the distance from the baseline to the center is 0.3em
|
|
! * The image is placed on the baseline
|
|
| * The line box has to include the image and the middle of the font
|
|
! * Thus the line box is 0.3em high
|
