makeFontSizer()Spanprivatestatic

Makes an element placed in each of the vlist elements to ensure that each element has the same max font size. To do this, we create a zero-width space with the correct font size. // Note: without this, even when fontSize = 0, the fraction bar is no // longer positioned correctly

pos string

The method that will be used to position the elements in the vlist.

One of:

  • "individualShift": each child must be followed by a number indicating how much to shift it (i.e. moved downwards)
  • "top": posData specifies the topmost point of the vlist (>0 move up)
  • "bottom": posData specifies the bottommost point of the vlist (>0 move down)
  • "shift": the baseline of the vlist will be positioned posData away from the baseline of the first child. (>0 moves down)
