Website vs. web page. A website (usually one word, though a few publishers use Web site or web site) is a collection of linked documents and content associated with a single organization, person, group, or topic and usually sharing a server and a domain name. A web page (usually two words) is a single page of content on a website.
The Marvel Netflix shows seem to take place around the same time as they were filmed. Iron Fist filming happened April-October 2016. Clues in the show point to the season happening over the course of a month, maybe a month and a half, so I'd say it takes place right before Civil War.
The series will be set in the Marvel Cinematic Universe and tie into series featuring Daredevil, Luke Cage and Jessica Jones and will culminate in a Defenders series. In January 2016, Mike Colter told Collider that the actor for Iron Fist is already cast. In February 2016, Finn Jones was cast as Iron Fist.
