Hi

I was used to write this in the CSS file

Code:

sup { 
 vertical-align: text-top;
 font-size: smaller;
}

and be happy with it. For some reason, it does not seem to display so well recently(including with Calibre but not only). I had used text-top because super left too much space between lines.

What would be the reason for a faulty display of the above code?
What would be the other proposals for ePub3 books?

1. Trust the user agent? (with a "naked" sup tag)

2. When possible, use special characters such as SUPERSCRIPT TWO (\00b2)

3. With suitable font, use open-type alternates such as:
font-variant-position: super (text-top?);
font-variant-numeric: ordinal;

4. ?
