As long as there is only at most one pseudo-element per selector, it
doesn't matter whether you assign a specificity to them. Selectors
with a pseudo-element never compete with selectors without, because
they don't apply to the same elements.

    :first-line { color: red }   /* specificity 000 */
    #x1 #x2 { color: black }     /* specificity 200 */

    <div id=x1><div id=x2>Some text...

The first line will still be red.
