css - getting rid of space with the superscript in html emails

Question

superscript is leaving a big space between the line height.

code is

<span style="position:relative; bottom:0.2em; font-size: 0.8em">&reg;</span>

I am not using the <sup></sup> tag as it too leaves a big gap in the line height.

Is there a work around. I am aware that the position:relative does not render well in outlook. What's the other alternative to this?

Answer 1

I've made few experiments in jsFiddle and I think you will be able to use:

<sup style="line-height: 0">&reg;</sup>

in firefox it does not increases the gap between the lines
