Unlike offsides in American football (whereby the defender is on the wrong side of the football at the snap), offsides in soccer is about proximity to the goal. Simply put: If you are closer to the goal than the two closest players (including the goalie) on the opposing team, and the ball is not between you and the goal, you have committed the offside offense. You cannot, however, be considered offsides if you are on your team's side of the field or during a corner-kick situation.
