The difference is that fontsize is set in the CSS in the first 
place. However, the "strength" is *attribute* for the element and 
CSS cascade order says that you have to apply the style according to 
structure and element's attributes. So you have an element with 
structure HTML > BODY > DIV > EM > SPAN > SPAN > EM and its strength 
is 2. Which color the text inside it should be if I have styles

em::strength(2) { color: red; }
em::strength(3) { color: green; }
em::strength(4) { color: blue; }


(Suggest another selector if you think there's some better one. I 
definately think that not having to nest EMs to make them stronger 
isn't that bad so to require ::strength pseudo class. The selector 
[strength=2] isn't a good one because that makes the strength 
attribute absolute and the nesting information is lost.)
