First, a code example would be a good idea, because there are many details that we need to know. (e.g. what other divs rely on div (1) position?)
You cannot overlay divs in box-model or inline (model).
You can try using negative margin to move div (1) through div (2), but this is not an elegant solution.
You should reconsider the use of absolute positioning, as this is clearly the preferred solution.
