- Add “mso-line-height-rule:exactly” to the paragraph’s inline style attribute where you want the superscript to display.
- In the <sup> tag’s style attribute, reset the line-height to 0px
- Take the font size you have set for the paragraph and reduce it by about 60%. In this example the superscript font size would be 12px when the paragraph font size is 20px.
- Now subtract that value from the font size -> 20px – 12px = 8px
- Use that amount for the vertical alignment on the superscript.
