roger64, do use .75em if you want your smallcaps and not .7em.
0.7, 0.75 or 0.8; this doesn't make much difference, it's just a matter of personal taste. How to name the class is of minor interest. I just used a quite common term, which is pretty selfexplaining.
The point is, that the letters within the <span> MUST be converted to uppercase (Look at your example a few messages above (#5)). This is the major difference between small caps (Font) and fakesmallcaps.
