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.
In March 2014, Loeb initially stated that the Iron Fist series would begin filming after Jessica Jones as the third of the individual series. By March 2015, it was expected to be the fourth of the individual series, entering production following Luke Cage.
