If statement #3 above is passed, then:
The first letter of this paragraph should be yellow; all other letters should be UA-default. The rule applied is "P.initial:first-letter {color: yellow}", which has the pseudo-element at the end of the selector(THIS IS PROPER). Notice that the first letter of this paragraph is not blue; there is another rule in the source as "P:first-letter.initial {color: blue}", but this rule is ignored, since the pseudo-element is at the beginning of the selector(THIS IS NOT PROPER).
This link should be lime if unvisited, because of the pseudo-class "A:link:first-letter {color: lime}", where the pseudo-element is at the end of the selector(THIS IS PROPER). This link should be UA-default if visited, because the pseudo-class "A:first-letter:visited {color: blue }" has the pseudo-element in the middle of the selector, not the end(THIS IS NOT PROPER).
