I should know this, but need clarification anyway

I've seen where different leagues use front of base tackling or any touch. I play any touch because that was my first introduction in league play.

For some reason I was thinking that front of base tackling meant that if the front of the ball carrier's base hit any part of the defender's base, he was tackled.

But it should be the front of the defender's base hitting any part of the ball carrier's base for a tackle. Correct?
