fergald has just created a new issue for https://github.com/w3c/csswg-drafts:

== [selectors] nth-child omits n=0 case ==

"The An+B notation and its interpretation are defined in CSS Syntax 3 ยง6 The An+B microsyntax; it represents any index i = An + B for any positive integer n."

So e.g. 2n+1 would not match the 1st child.

The link is to


"The An+B notation defines an integer step (A) and offset (B), and represents the An+Bth elements in a list, for every positive integer or zero value of n, with the first element in the list having index 1 (not 0)."

The spec should mention the zero case (and probably also that the list is 1-indexed).
