EDIT:
Okay! I added the new code that fixes all the font size, color, style, face, weight, etc issues...
Here is the new replacement code.. it is also in the original post now:
Code:
<button style="background-color:transparent;border-width:0;font-size:inherit;font-family:inherit;font-style:inherit;font:inherit;font-variant:inherit;font-weight:inherit;text-decoration:inherit;text-transform:inherit;text-shadow:inherit;color:inherit">
<center>
<sub><font style="text-decoration: underline;">{option}</font></sub><br>
<sup><font style="text-decoration: overline;">{param}</font></sup>
</center>
</button>
