Free throw lane marked spaces

[shont]

A player that is in a marked lane space. May they break the plane of the lane line with their foot before the ball hits the rim, or do they actually have to make contact inside the lane before the ball hits rim for there to be a violation? Also what about the lines that mark the lane spaces, can they have their foot touching this line, or do they have to be entirely within their space? I am talking about NFHS rules.
