it doesn't explain the openings in any detail but it does give a 1 line explanation as to why each move is made. I find that by flicking through the opening lines I see the purpose of the earlier moves. It's a good site but limited to the major openings.

Try the book: "Ideas Behind The Chess Openings" by Reuben Fine.
Clear and consise, still a classic. Won't go hugely in depth, but explains common pawn structures and the more common variations.
