How to implement CSS multi-level drop down menu with different classes?

I understand what you mean. And I am pretty sure that the styling to which you need an answer to, which works for all except for the one at the bottom, has arisen purely by accident. (Kind a nice one I must say).

I am almost certain of this, because your code as well as the file names lack any form of consistancy. There is double code, there is superfluous code, and there are images missing.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
