For a project I need to build a carousel of html pages loaded into a modal, like in the example in the image below.
Some other features requested are:
- partial visibility of previous and next carousel steps ability to
- force the open of the lightbox with the carousel exactly in one specific step and not always at the first one
- auto-height of the carousel steps, not a fixed one
- hide of the prev(next) arrow for the first(last) item
My idea is to treat a single step of the carousel as a single external html page, but I’m open to every suggestion.
So, the question is: what is the best way to make this? 
Thank you so much in advance, any help will be strongly appreciated.
Here’s my personal favorite:

Works great, highly browser compatible (when done right), and easily customized.
Just lay it over a semi-transparent fixed div and your set.
