In a general sense, here is how you can load html from an external file into a div, beyon that, I am not quite certain what you are trying to do exactly.
I have the exact same problematic, I have written something that displays the popup but partially renders the CSS edit a few more tries and I was able to make it render CSS perfectly.
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.
