First, the all declaration that apply to the element are found. The
element in question is 'p.initial', so declarations with 'p' and
'p.initial' apply. 'p.initial' has a higher specificity than 'p', so
'font-size: 12pt' will be discarded. The text indent ('3en') will
therefore be based on a font size of 24pt. 'en' is then 12pt, and
'p.initial' will be indented 3 * 12pt = 36pt.

Assuming you mean:

 > html {font-size: 8pt}
 > p {margin-left: 3en}
 > p {text-indent: 3en}
 > p.initial {font-size: 24pt}

The same rules apply here: 'margin-left' will be based on a font-size
of 24pt and will end up being 36pt.

 > How does :first-line fit into this?

:first-line should not be used to set indentation on the first line,
'text-indent' is meant for this. This will more explicit in the next
version of the specification.
